However, there's no denying how awesome it is that a few college kids can raise over $100,000 like this to build their project.
Even if the project fails like most people say, I imagine it will be a positive experience for the four guys that worked on it.
I figure it will be a huge hit among geeks like us, but then will fall out of usage due to the lack of updates from people that matter, like friends and family.
I use Facebook for staying in touch with the mostly non-technical people in my life who actually use Facebook, and that's what will end up swaying most users (like myself) back towards Facebook in a relatively short period of time.
You won't switch if you don't have anyone to talk to on it, and you won't have anyone to talk to on it if you don't switch.
Google Talk and its Gmail integration did wonders for Jabber, thankfully.
I take recommendations I give to people very seriously, and I simply wouldn't recommend to any non-technical person to move away from Facebook to a platform that has none/few of their friends on it.
