Today I found two bugs in this site and asked questions about them. My questions were marked as duplicates. That's fine. Is there anyone who views those and fixes bugs in this site?
Both the developers and the community team regularly patrol every meta site in the network, to make sure that all valid bug reports get attention (among other things). Sometimes, things don't get tagged correctly, but we do often catch those relatively quickly as well.
The order in which bugs are fixed, delayed until another bug is fixed, or put on the back burner for being very low impacting is completely up to the developers - they want to make sure that they're satisfying the broadest group of users possible with their work.
Some bugs are valid, but not very noticeable, and may remain unfixed because it's known that a major change coming up relatively soon is going to make them a bit of a moot point to begin with.
However, we do try to acknowledge each one, and provide feedback on them. If a bug is a duplicate of another, chances are the feedback we've given is on the original - so be sure to check there. If there hasn't been much movement since, you're absolutely free to
@mention one of us and ask - we're pretty good at responding to that.
There's also a contact link in the footer of every page on every site - if something that seemed minor went major, or you think something just didn't get noticed, you're always free to get in touch with us.
To directly answer: Yes, every (valid) bug report counts.
That gives us 4,461 bugs fixed out of 8,068, or a 55.3% clear rate on reported bugs.
So yes, they do get fixed.
