As we all know, "voting is different on meta": since there is no reputation attached to votes, it's possible to freely upvote or downvote questions and answers based on whether you disagree with them or not. (The FAQ says this is only for feature requests, but it appears to have been taken as a general principle.)
The problem is that when a question is downvoted below -7 or -8 (not sure about the exact number), it disappears from the front page altogether. But having seven or eight people disagreeing with you doesn't mean that the issue shouldn't be discussed at all, in my opinion. It can also happen that the first people who stumble on the question disagree, but later other people could have agreed.
I guess this was implemented to weed out evidently terrible questions from the front page of the main site (where the volume justifies it). But the volume on meta is much lower, and in general I dislike attempts at shutting down the discussion on meta (except in cases of duplicates or completely off-topic questions) -- otherwise there's just no place to discuss it.
I can see a few options:
- The current situation is OK for everyone;
- Downvoting shouldn't mean disagreeing anymore on questions;
- Questions shouldn't get thrown out of the front page when they gather a large negative score.
Of these three my preference goes to the third one.
