Unsurprisingly, the span of reactions was very mixed when Twitter doubled it's character limit from 140 up to 280 characters. With from what I can tell the largest amount of the people who I follow and also the loudest ones around general discussions being rather negative, mocking the change and lamenting that Twitter wouldn’t understand its own social network.
But what I’ve also seen a lot in this context, probably the second largest amount of comments, were tweets from people, who were more neutral towards the new character limit and instead pointed out how they would much rather like an edit functionality being introduced. Which, again, in several cases lead to replies from others explaining how this would be an even worse idea. Some of these conversations also were kinda constructive and came to results such as that a short time interval after sending a tweet to correct typos might be acceptable.
Coming from Google+ and seeing how editing also got through without constant and big hazards on Facebook, I really also don’t think it would be a big deal on Twitter also without time limits.
Nonetheless, I want to show with this concept an edit functionality that would even fulfill the demands of more cautious users, who believe that normal editing unlike on Google+ and Facebook would be more problematic on Twitter, while not restricting the feature in terms of time or how often tweets could be edited.
