[META] Voting Etiquette

Question

Under what circumstances do you vote a question up or down?

Let's have a little discussion on voting and friendly behavior.

Asking and answering questions is not the only way to participate on BrewAdvice. The thing that differentiates this site from a forum is the way good questions and answers sift their way to the top. Voting makes this possible.

Answer 1

1. Any time I give an answer, I upvote the question ^†
2. Commonly asked questions (like recurring forum questions) get my upvote
3. If I think the question is relevant, clear and concise, I upvote it
4. When the question is irrelevant or general, I downvote it
5. I am more likely to upvote a question from new registered users
6. I am less likely to upvote a question from unregistered posters

† Except in cases where I am prohibited to upvote, like my own questions

Answer 2

When I think an answer is good or is similar to the answer I was planning on giving I upvote it (and I now add a comment [since I got that ability] to expand on the answer if I feel it's necessary/useful).
