To be honest I suspect they wanted to do this before, but the power mods wouldn’t allow it. I definitely remember the staff posting a proposal to allow second chances for closed questions, and it was downvoted to hell by the mods. They presumably got scared because they were getting a lot of free labour from the mods (even if it probably wasn’t exactly the kind they wanted).

Now StackOverflow is dead the mods have no power, so they are free to make changes.

The company is going forward with it because the “active community” killed their site and now they have no choice.

If they had done it before AI became a viable alternative they might still have some users.

I would say it maybe makes sense to do that for team based projects so your TODOs don’t impact other people finding new warnings in their code.

For solo projects I don’t think that makes any sense.

Deno is great. The best way to write web site and static sites IMO. I really hope they survive.
