In terms of voting, the Meta FAQ mentions:
Voting here works a bit differently from the main site. On Meta, voting is often used to express agreement or disagreement, not to point out a lack of quality or helpfulness. Please don't be concerned if you receive downvotes – members of the community may simply disagree with your bug, feature request, support issue, or the nature of the discussion.
However, when I view my activity "fly-out"
there is no way (at least I could find) to identify the posts of mine that received the votes. For example, which posts do the +2 above refer to? How else would I know that I'm awesome or not so much?
