Is innovation in adult dead? And why?

[Hell Puppy]

The adult side of the web used to be extremely innovative. There have been lots of new concepts and inventions for both types of sites, business methods and marketing done in adult over the last decade plus. Think about how many you can quickly name, both good and bad?

Now how many can you name that have been invented in the last 2 years? 3 years? Heck, even 5 years?!??

Meanwhile, mainstream seems to be kicking our ass over the last couple of years. There's constantly some neat new idea for a site out there from Digg to Twitter to Jaiku to all of the cool stuff that Flicker has been adding. And let's not forget Myspace, Youtube, etc.

Why?

My theory is most of the innovation right now is being driven by "Web 2.0" (i hate that term by the way). But for community and collaboriative user participation sites like these to work, you MUST have the trust of the user and not just try to slip your hand into their back pocket and take their wallet. That's something most of the companies currently driving the economics of the adult web do not understand.
