According to several sources Twitter is in early talks with Google and Facebook about a potential buyout. The talks are very early at this point and haven't gotten serious. It looks more like Twitter is currently exploring its options and gauging interest from these big companies. The company is reportly estimated to be valued at $10bn, up considerably from last years valuation of $3.7bn. With such a valuation many are wondering if Google or Facebook would really pay that for a company when it's still making a loss.
The forums at WebmasterWorld are buzzing about this, with many who think the company is overvalued and want to see it remain independent. According to StoutFiles:
There's a reason Twitter's talking with those companies, and I bet it has something to do with the fact that they don't make money and have maxed out the idea.
Others think it makes sense for Google to potentially buy Twitter. It could be the traction the is needed to give it more broad acceptance and usage than it currently has. One member goes so far as to say it would be better buy for Microsoft in order for them to stay competitive. Maybe so. Whatever Twitter ends up doing, I hope they justify a buyout for more than just the money.
