Seems like this is crazy expensive from a PE perspective. especially when I don't see how much long term value a site like this has that can easily be replaced by the next big thing.
Maybe a year plus from now when everything settles I will re look at it but this just seems like gambling at this point.
I agree with your gambling point, but I disagree with the easily replaced point...
Facebook's move to the timeline layout was honestly ingenious...simply because it put the "history" that is on facebook in perspective. I was clicking back through my timeline, and I got to 2007, when I first joined. I found the entry where my wife and I became facebook friends. I could go back and read status updates from a much earlier time that reminded me of things that I had forgotten about. It really made facebook not only a social media outlet for your current life, but also a chronological record of your past as well...that's not easy to just walk away from. I think that it won't be as easy to switch to the next big thing as it was for Myspace because facebook has history.
