I'm surprised Twitter's stock has floated as long as it has. While Facebook has diversified into different, successful, products and platforms, Twitter has stagnated, fumbled around and underwhelmed. Much like Yahoo. Perhaps I'm just a bit cynical and biased against Twitter though. I find the mostly arbitrary 140 char limit, 6 second video communication concepts a cute gimmick that will eventually tire. I wouldn't be surprised when the tech bubble bursts, these social media experiments will be the first to fall back to earth. Any significant slashing of advertising budgets (due to e.g. macro economic affairs) will seriously strain the revenue model (and investor patience) of these services.
