Meta is about asking about questions, it's not for asking off-topic questions.
Questions need to be able to have a chance at a single acceptable answer that is also going to be useful to others. Asking for opinions and people's experiences are just not a good fit on a Q&A site.
This usually happens when posts and suggested edits are attributed to the Community user (as part of the procedure followed when deleting a user). This will eventually be fixed by a scheduled task and the reputation will go back to 1.
