Twitter is making a small change that could have a big impact for users. Users have been limited t0 140 characters for each post.
If you’re replying to a post, the address of the person or group of people you were replying to used to count toward your allotted number of characters. Now, those names will appear above the tweet, giving you room to get a few more words in.
Just tap on Replying to see who’s part of the conversation.
