I predict Google will pick up Twitter. Google is one of the few companies that can sustain internet businesses without a business model because anything that encourages more internet use indirectly helps Google.

In my opinion, Google is still a strong exit strategy for many years to come. Google has $7 B in cash, $29 B in assets and only $3 B in liabilities.

Of course I would never build a business with Google as an "exit" strategy, but I think that's the best option that Twitter has. Sure you can argue for the corporate spin, but I personally feel that is a weak play (like someone else said, there are a million other corporate collab startups out there already that can clone Twitter).

It makes even more sense since Evan Williams (founder of Odea, parent company of Twitter) sold his previous blogging company, Blogger, to Google.
