Even with all their recent updates, designed to steady their rocking user base – like finally paying attention to the lack of interest in Twitter's photo features, the search partnership with Google, the latest update for iPad and so on – the plateauing user base and underwhelming performance on the stock market. The verdict, from Victor Basta, at least, is that Twitter is a 'dumb pipe' and the smartest thing to do would be sell. The fact that Twitter still has an interim CEO, added to the recent announcement that Mike Gupta, earlier Twitter's CFO and recently in charge of Twitter's venture section, is leaving to be CFO of Dockers, won't inspire any confidence in doubters. But what would we do if it got sold and shelved? Granted, even if it were sold, it's very unlikely that it would be shelved. But still, can we even imagine life without Twitter?
