Twitter poised for paid accounts and advertising

Technology is a strange business because it has a lot of financial backing before it even has any way to make money.

Take Twitter, for instance, which has grown to around 58 million users but doesn't seem to have a real business plan. That seems to be changing now that Twitter co-founder Biz Stone told reporters the social media darling is planning to start charging companies for using its platform. The new accounts will be rolled out in 2010.
