Post History

No, making useless edits just to bump the post isn't something that we want to encourage on Codidact communities. Edits should be to improve the post and that's it.

Looking at the reasoning for bumping, though, there are two main factors: To earn votes, and to get a response.

While we do currently have a reputation system - earned through votes - we're working on deemphasizing it. Privileges are not tied to reputation; instead, there are Abilities you can earn. The "bump to earn da pointz" is mitigated slightly here over Stack.

As for the other factor - getting a response - that's something we still need to work on. We do need to figure out some way to highlight posts that haven't received a response yet and that may not be immediately visible due to their age.

However... I also want to caution against bringing up too much hypothetical situations. Have you encountered this issue on any Codidact community? 
Unless you've encountered a problem on Codidact itself, we don't need to address every edge case and scenario that's popped up at Stack over the past eleven years. As our platform and *modus operandi* are different, the problems we'll run into are going to be different from Stack's. We don't need to make a decision or address everything in anticipation of running into Stack's problems; we can address things as they organically appear.

(That's not to say thinking ahead is a bad thing. It's not. But we don't need to think ahead about every small issue that could come up; let's think ahead about some of the larger things for now.)
