Twitter just announced some big changes happening, which will allow you more room for your 140 character limit!
“In the coming months we’ll make changes to simplify Tweets including what counts toward your 140 characters, so for instance, @names in replies and media attachments (like photos, GIFs, videos, and polls) will no longer “use up” valuable characters,” Twitter announced. “More room for words!”
In addition to the @name replies and media attachments, you’ll now also be able to retweet your own tweets. The biggest change of all may be the famous “.@,” which will no longer be necessary. You will be able to start your tweet with an @ username and not put a period in front.
