The lack of money making reminds me of a situation from several years ago regarding one of my web hosts.
They offered hosting for free, no ads, fast servers even free phone support. Then one day they went from free to cheap. Because they where good the choice was obvious, pay. If even 5% of users paid they became a strong viable company.
Would 5% of twitter users be willing to pay?
