Twitter is testing Notes, a new publishing option with no character limit
It took quite a while, but Twitter eventually decided to increase the maximum length of tweets to 280 characters. For some people, this is still not enough, and threading is not for everyone. It is with this in mind that Twitter has started testing a new long-form writing format called Notes.
Twitter has long been referred to as a micro-blogging service, and Notes takes things to the next level, essentially giving users the ability to write blog posts of any length. As well as eliminating the character limit, Notes can also include photos, videos and even embedded tweets. Best of all, Notes are editable. This may not be the "edit tweet" option people have been looking for, but it is a step in that direction.
