Already struggling to fit your message into 140 characters? How about stuffing it into 117?
Come February, tweets that contain URLs will be reduced to 118 characters and 117 for https links. The change only represents a two character difference, but sometimes those two little characters can be pretty important.
Twitter is making some changes to the t.co link wrapper which will extend the links to two additional characters. Ultimately, every link will take up more space in your Tweet and reduce the text in your message.
The new links won’t go into effect until February 20, 2013.
