Waiting for the Next Bubble to Burst

I'll never understand Web 2.0 companies. To be honest, they've always seemed like the hipster children of the dot-com bubble--like the brains behind flooz and kibu got together over drinks and decided to have another go. Take, say, Twitter. It's hard to fit in even two full sentences, and yet somehow it's reasonably successful--or at least, "all the cool Web 2.0 kids are doing it." What's their corporate model? From whence comes their funding?

I bring this up because I just came across spinsnap, which touts itself as "channel-surfing the internet." First, this concept seems familiar--I could be wrong, but I feel as if I came across something very similar a few years back. It's an interesting concept and is clearly ad-supported, but I cannot for the life of me figure out how this website will stay afloat. The sites they include on their randomized list don't seem to be sponsored--that is, anyone can suggest any site, though I'm reasonably certain they're trying to keep porn out of it. (Or not--adult friend finder just came up.) Really, though, what is this? "Hey, I have an awesome idea! Let's get ad sponsors to help keep very bored people entertained! We'll model it after Google's 'I'm feeling lucky!' function, only without even giving it the guidance of a search word!" It just doesn't seem sustainable.

To spinsnap's credit, they have an interesting implementation--you can search by websites, by music, or by people. Music seems particularly interesting to me. Really, this tirade is against Web 2.0 corporations in general. I honestly wouldn't be surprised if there's another bubble burst in the next year or two, as companies realize their services aren't really all that useful and as they discover that their costs outweigh their profits, and therefore start quietly pulling their services away. I have little doubt that this movement will be replaced by one that will ultimately prove equally unstable, of course, but one can hope.
