Gone are the days that you can create a network and simply exist on advertising revenues; markets today demand constant growth in the user base too.  Back in 2002, a then Social Media entrepreneur said to me "The winner of the game is the one with all the names", and on that basis, Facebook looks to be way out in front.

Twitter's 'product' is still hugely valuable, and is now a recognised part of how we communicate, find news and network online.  It's even replaced email in many areas.  However, with job cuts ahead and buyers seemingly uninterested there are challenging times ahead for Twitter.

Only time will tell what will happen, but I am already hearing some marketers suggesting that brands should start to look elsewhere if they are currently heavily reliant on Twitter.
