Many many times I've posted some tweet just to realize, one second later, that I made a typo. I've always thought about the need of a Twitter undo function, or at least edit, to avoid these embarrasing moments.
How could this work? A few seconds to have the chance to modify what you just tweeted perhaps?
I always check many times before tweeting anything but even so there are mistakes.
What do you think? Do we need Twitter undo?
