Unlike GitHub, tweets should not be editable forever. I think 5 minutes is reasonable. Even HN has an edit time limit. I hope they also limit how much you can tweets (even though, in reality, adding 4 characters (“not ”) is destructive enough.

Do you think HTML pages should be uneditable after a period of time? Regardless of your opinion there (since I can see the merits), the rest of the web isn't exactly founded on immutability.

But Twitter doesn’t want to be just another webpage. Tweets and its dates are used in court and by historians. That’s basically why Twitter has been hesitant to allow edits.

I kinda wish they let people add some text instead of allowing editing, like:

    Wouldnt it be nice?

    Added: * wouldn’t

I know deletions are still allowed, but they don’t lead to different content.

I see the argument, though. Edits in a conversation break context and flow.

I think the other option would be to have a longer window, but then have edits of “popular” tweets require a manual review and approval.

Links and uploaded media should not be editable.

Then you need to hire humans and it costs money. An edit history is much cheaper.
