A month after Twitter doubled its 140-character restriction for people to express more in a tweet, users were divided on the new 280-character limit with only 38 per cent approving the change, a new survey has found. According to the survey by London-based market research company YouGov, four in 10 said they liked it more now that tweets could be 280 characters long, while around a third (32 per cent) said they preferred it when tweets could only be 140 characters long.
