You should make your own judgement about whether or not a question is on topic and vote accordingly, regardless of whether a moderator interacted with the post.
Mod votes for closing, etc., take effect immediately, so we tend not to vote unless:
- several others have already voted, and we agree with those votes (so it's effectively weighted more like a regular vote)
- we think it's definitely not a good fit and needs to be closed ASAP to avoid attracting low-quality answers
For this question, I saw that it had a couple close votes for being a "What should I do?" question -- but also that the sentence containing "Should I?" could be removed without really losing much. So, I went ahead and made the edit. My hope was that by removing those words, reviewers would be more careful about deciding whether or not it really was a "What should I do?" question at its core -- so thank you for that!
Even if a mod straight up says "I think this is a quality, on-topic question", you're always free to vote to close if you disagree. Stack Exchange sites are shaped by all users in their communities, and sometimes we'll have different ideas of what's on-topic and what's not. If the user you happen to disagree with is a mod, that's fine too! We're still human ;) If there's four others on your side and the question gets closed, the most likely result is that we'll ask for opinions in chat or make a meta post (like anyone can!), which will help everyone by setting a little more precedent and clarifying what we can agree is on topic and not.
Like Cashbee mentioned, mods frequently also edit to fix grammar, spelling, and formatting, without significantly changing the substance of the post. Sometimes we also copy-paste content from the OP's comments, so that the comment section can be cleaned up. So, just seeing that a mod was last to edit doesn't necessarily imply anything about the quality or on-topic-ness of the content - you can click on the edit history link on a post to see what exactly was changed and compare against the older versions, and decide for yourself.
