Reports states yesterday 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.

Now every day more than 300 million regular Twitter users send hundreds of millions of messages – news reports, personal updates, advertisements, political pitches, photos and videos and, most often, just witty and innocuous comments.

Media reports says that the company already allows 10,000 characters in a commercial product called Direct Messages, so the technology is no longer a barrier. The company is testing a version that would still only display 140 characters in a message, but carry much more, and a reader would have to click on the tweet to see the rest.

The move is a part of Twitter's efforts to expand its user base and advertising sales and other sources of income. Twitter itself had no comment on the report yesterday, but users were not entirely enthusiastic about the possible new limit.
