It all depends on what kind of person you want to be seen as, or be. There are many users who don't interact at all, just post as an excuse to circular or self-vote. There are people who allow rampant self-voting for relatively big money of junk comments in their threads, because they're established people who upvote themselves and no one else and no one in the thread is really trying to talk to anyone, but rather just find a convenient place to hide the self-voting. Then there are people who interact with others like normal humans, and there are a select few authors who are very generous with voting users who reply in an intelligent fashion.
