WASHINGTON, D.C.: Twitter’s 140 character limit on tweets has long frustrated and challenged its most verbose users. Now the company could offer a solution, according to tech news website re/code: the 10,000 character tweet, which could be available as soon as March. Re/code reported Tuesday that Twitter has been studying how to allow users to say more, after restricting them to 140 characters for 10 years. That limit was based on the capacity of the original messaging software used, and though frustrating for many, unleashed a tidal wave of ultra-concise commentary across the web. The move is a part of Twitter’s efforts to expand its user base and advertising sales and other sources of income.
