I think Facebook is fine. For all the yammering about how going public is forcing them to change, the reality is that FB is just doing what FB has always done- trying things out and promoting their vision of sharing. Some plans work, some don't, but it's nothing to do with chasing revenue. Lazy common wisdom narrative is lazy.<p>Twitter, on the other hand, seems like it's destined for a crash. Not yet, they haven't pissed off the users yet, but they're headed in that direction. They're clearly taking control of how tweets are consumed with a plan to make them more annoying via revenue seeking. It's going to be a mistake.<p>Facebook has tremendously strong user lock-in, which people here tend to dramatically underestimate. It's a true social network of people with mostly real-world ties. Moving people off that will have to take place en masse or it won't happen.<p>Twitter, though, has very very weak lock-in. Unlike FB, the most use of Twitter comes from a small number of accounts. The entire service is driven by a handful of percent of the users. If they leave, the service is dead. And they'll go whereever they can build an audience.<p>Google+ stands to gain from Twitter's missteps, and that's where they should be aiming. G+ has zero hope of taking on FB, but they could siphon off Twitter completely once Twitter starts pissing off the few users who matter there.
