A bit sad, as a member of a big project on github, I'm sure that "starring" could be a handy way to know what people are interested in. (And avoid a lot of "me too"-comments, from devs and other users alike).

I think Google Code does this one right: "Subscribe" is a star and you get notified -- star counts are public. I hope github adopts that model.
Do you mean internal discussions? What is the main reason to not support voting?
Priorities are a necessity for large projects. One could use a full-fledged issue tracker, but having an integrated one in GitHub would be miles better.
You can set create `priority:1`, `priority:2`, etc labels right now and sort by those values. Not quite the same as what you want, but it's a pretty close solution until we figure out the next features to add to Issues.
