As a fan walked out of the Slayer concert Tuesday night at Saltair, he seemed surprised if not almost a little disappointed.
"They're not as evil as I thought they were," he commented.
That's an interesting comment that might reflect as much on metal fans jaded by bands like Slayer who are not afraid of being extremely politically uncorrect. These days, it takes a lot to shock and awe a metal fan.
What is to be made of this 25-year-old thrash metal band which spews hatred of all things religious and inspires its black-clad fans into mosh pit frenzies that are not all that different from the kind of gyrations one might expect to see at a Christian tent revival? Is it a slick, cynical commercial enterprise that uses devil worship, Nazi symbols and loud ear-shattering guitar, drum and bass riffs to play to its fan base? Or do group members Thomas Araya, Kerry King, Jeff Hanneman and Paul Bostaph really believe what they say and promote? The group, ranked with Megadeath, Metallica and Anthrax as the greatest of the 80s' big hair thrash bands, certainly doesn't shy away from controversy and definitely would be offensive to many religious beliefs.
Starting the concert with a chorus informing its adoring, gyrating and chanting fans that "God hates us all" and later singing from their latest album Christ Illusion that "religion is hate, religion is fear, religion is war, religion is rape,

relgion's obscene, religion's a whore", the group left little doubt where it stands on the subject of God.
Of course, actually hearing any of the words Araya screams into a mike during a concert would be a challenge. While fans could be seen shouting along, it is possible to only a actually discern a word or two in the din of pounding guitars and drums with bass loud enough to shake the rafters.
In some ways, that's a pity because, in Christ Illusion, Slayer has some interesting and controversial things to say about not only religion but about the post traumatic stress syndrome suffered by soldiers returning from Iraq and the motivations behind the 9-11 terrorist attacks.
If one of the purposes of rock music is to challenge the established order and make those willing to listen think just a bit, then Slayer remains relevant.
Of course, I doubt that most of the nearly 3,000 fans who came to see Slayer and opening act Unearth pondered such philosophical musings. Most of this male-dominated crowd came to rid themselves of testosterone and beer-powered energy in the mosh pit, enjoy continued shouting of variations of the f-word and repated chantings of the band's name.
Most seemed to thoroughly enjoy the experience.
Slayer can and does put on a 90-minute show packed with hits, flashing lights, pounding guitar licks, slick choreography and plenty of smoke.
From a distant part of the cavernous Saltair, Slayer lead vocalist and bass player Araya resembles a deranged Charles Manson, a look that may or may not be accidental considering the numerous devil references in the band's album artwork and lyrics.
The pounding guitar and bass licks and two-bass drum throbbing work of Bostaph coupled with lighting effects designed to enhance the madness of a venue that sells all general admission tickets and offers no one a place to sit gave fans something to shout about.
And shout they did. Considering the body surfing, violent moshing and number of coats, hats and assorted plastic bottles flying around in the air, it's a good bet that many a Slayer fan woke up a bit on the sore side Wednesday morning.
Being cynical about Slayer's intentions to stir controversy aside, one could only leave Saltair Tuesday night marveling at both the energy displayed both on stage and inside the arena as fans and band members alike seemed to let off more than a little anger.

NBC may be late to the social networking soiree, but it may wind up being fashionably late and bringing a tasty artichoke dip. The General Electric (NYSE: GE)-owned broadcasting network clearly has a lot of catching up to do. It's not like FOX parent News Corp. (NYSE: NWS) with the timely acquisition of MySpace. It's not even like Disney (NYSE: DIS) with its new Disney.com makeover that will transform the popular site into a family-friendly destination with social networking enhancements.

NBC is alone. It's on the outside looking in. If you ask me, I think that's a pretty good place to be. You can't beat the view and the chance to learn from the mistakes of others.

Over the weekend, the always-provocative Tech Crunch blog unearthed a deleted blog entry by NBC Digital Media's Sab Kanaujia, VP of Digital Innovation. In the entry, Kanaujia detailed his company's approach to social networking.

Despite some advice from a venture capitalist bigwig that suggested making a big splash with a stand-alone social networking site like MySpace or Facebook, Kanaujia's slant seems to be to build social networking features on top of the existing online presence of its properties.

Kanaujia is right. You don't reinvent the wheel. Your best approach is to litter the information superhighway with nails and thumbtacks and then provide an alternate form of transportation to make your site the sticky hub of choice.

Enjoying the silence
FOX has been very careful to keep its MySpace destination wild and out of the influence of its televised properties. Like Google's (Nasdaq: GOOG) YouTube, the allure is that the fat cat parent hasn't tried to blatantly commercialize the democratization process.

Would NBC love to have the nearly 40 billion monthly page views that MySpace is generating for FOX? Sure, but not having that gives NBC the luxury of starting from scratch with a blank slate instead of being tempted by the forbidden low-lying fruit.

Just think about the possibilities.

Picture a community site for The Office where registered guests can hang out in a virtual Dunder-Mifflin. They can share their workplace horror stories or their views on inter-office romance, but there's more to it than that. Personality quizzes that help you discover the cast member that you resemble the most? Sure, and don't forget the related avatar that visitors will be able to use as a signature file elsewhere. A weekly game casts you as a Dunder-Mifflin intern with a specific task to complete? Of course.

NBC has an opening here. That's what she said. Now it's up to Kanaujia to see if crafting the logical online watering hole for millions of fans can somehow be transformed into a major destination that will ultimately feed into job listings and selling office supplies in a few years. Oh, it can happen. Just because you haven't seen it doesn't make it impossible.

The biggest winner
NBC is already taking steps in that direction. The network's site for The Biggest Loser isn't just an informational site for the reality series. The site offers community features, a viewer photo gallery, and a diet center complete with recipes and online weight loss calculators.

It doesn't have to end there. Every show, even if it's only a specialty hit, can feed into a vibrant community of like-minded users. The site for Heroes already features graphic novels, a message board, and rudimentary games. With the superhero series gaining traction, what's to stop it from teaming up with an online video game to unleash an addictive multiplayer fantasy game? Why isn't NBC's site for Friday Night Lights the new hub for high school football coverage?

NBC can't dabble in online gambling, but why can't its site for Las Vegas be a lucrative portal to booking vacation packages to Sin City and sharing poker table war stories? Call NBC, Expedia (Nasdaq: EXPE), before Priceline (Nasdaq: PCLN) gets there first. Any hit show like Law & Order that can generate several primetime spin-offs has the critical mass to create online whodunits and interactive sleuthing games.

Deal or no deal?
There's a flaw in Kanaujia's plan. No matter how excited I can get about gravitating audiences toward NBC with property-specific sites, what happens when a show gets canned?

Every party has to end sometime, but what do you do when you've allowed fans to bond at an even deeper level than the letter-writing campaign notch of fandom? Fear Factor was off last fall's schedule. What if NBC had erected a site loaded with viral stunt videos and extreme sports blogs that the community isn't ready to let go? Woe to the demise of the virtual Central Perk coffeehouse that would have had to shoo away its patrons with the end of Friends. Can the communities live on in that awkward retro state? That would be tricky.

Will we get to the point, in a year or two, in which a successful site will save the show? Even worse, will we get to the point, in two to three years, when a pilot show gets picked up on the premise of the kind of website that it can serve as the backbone to? If so, will NBC find itself making the wrong programming decisions?

Thinking it through a different way, maybe that's the kind of move that would lead to the right programming decisions. The tail is wagging the dog -- the fashionably late rhinestone-studded tail.
