!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

IMO there's nothing to keep in mind on everyday use. But these things are things to consider when deciding what to use in a mindful manner.
If your instance goes down, you lose all you posts. vlemmy.net was an instance and they just vanished recently. lemmy.fmhy.ml just disappeared yesterday, I couldn't find much info besides a post vaguely mentioning that their domain name got seized by the Mali government (idk why). Besides being shut down, also due to federation issues. beehaw.org has defederated from lemmy.world and sh.itjust.works, meaning you can't really interact with each other for the most part. Some instances like lemmygrad.ml and exploding-heads.com are disliked by many instance owners due to politics and got defederated so they are sorta on their own island.
Edit: Well... techically, your posts aren't lost, you can still find them in other instances. But your images are gone since images do not get federated (unless someone made an archive) and you lost the account and any direct messages, and you have to manually check if you want to see any comments to a post that you posted before it got shut down. Just a huge inconvenience.
Former vlemmy user here, was very miffed when it vanished without a trace and with no warning.
Honestly, I think Lemmy needs something equivalent to the Mastodon Server Covenant.
I dont have my account on lemmy.ml because my opinions do not align with theirs.
Also choosing an instance with servers close to you is a plus as well for loading times
Largely, I'd say it depends on the sort of engagement that you're looking for. I went with mine because I'm passionate about FOSS and think that, long-term, it's only sustainable by organizations that do not have a profit motive.
