Twitter has announced an overhaul of its famous 140-character limit, to make users’ tweets more consistent. When the changes are implemented, users will be able to use 140 characters, regardless of any space taken up by multimedia such as pictures or videos. Users will also be able to reply to tweets without the username taking up any of the character allowance. CEO, Jack Dorsey, told the BBC that the changes were made so that the social media site “made sense”, and that Twitter’s priority for this year was to “refine” itself. The changes come after the site’s active user numbers levelled off for the first time since its launch in 2006, a problem that Dorsey blamed on the service becoming confusing, but said that these changes would make Twitter simpler.
