Very interesting, but it really makes me wonder.<p>If Twitter is making money, why dilute the shares with investment like this?<p>I'm sure one response is 'so they can grow the company', but that seems like a bit of a hard sell at this point.<p>How big does a company like Twitter really need to grow in order to be successful enough that they don't need to take $300 million investment deals? I mean, they are already the #1 provider of 140 character communication.<p>What is next?
