The faster the innovation the easier it will be for Twitter to block out competition in the future, not to mention keep a significant runway going for expansion. While this strategy wouldn't be good for the average successful startup, Twitter is obviously one of the top dogs in the web space right now so they have the luxury to REALLY shoot for the stars. We obviously can't tell what's in their innovation pipeline over the next two years, so it's hard to make a judgement call like that. I mean look at Facebook, they don't see any reason to become very profitable yet.
