Often when cruising the latest questions or working through the review queue, I'll make an edit that only adds homework.
I see two problems, the first very minor, the second potentially insidious.
- Is this too minor of an edit?
- Is it safe to make the assumption that a post is homework?
I argue that the first point is a non-issue, because these edits would not fall into the same category as Should I have accepted a trivial add-homework-tag edit on this old question?. These aren't old questions, they're the newest ones under https://chemistry.stackexchange.com/questions.
For the second point, if the OP says "this isn't homework", it probably isn't worth fighting over (unless the post is obviously homework or is VLQ) and the tag can be removed.
I use the word "insidious" because it's like judicial activism. It could easily be used as a weapon. Homework implies bad things, so choosing to add homework to a question is sending a message of how homework is defined on the site.
Though, I would like to continue adding homework to questions that are on hold or just recently closed for being homework, but for some reason don't have the tag. These are questions that are obviously homework, ignoring some previously contentious ones that resulted in "experiments".
