It's the same community doing the upvoting on all of the questions, so I don't understand the inconsistencies.
There is one question which has four answers, one of them is mine and I think is clearly correct (of course). So I'm not about to upvote the other answers which I think are wrong, and I can't upvote my own answer. Yet nobody is upvoting any of them.
There is another question that someone gave a non-working answer to, and I submitted what I think is the right answer, and the non-working answer almost immediately after posting got four up-votes. I commented on it, poked holes in it, and finally the person answering admitted that it didn't work for all conditions. Yet, it's still sitting there at +3 (because I down-voted it).
Is this just a frustrating side-effect of effective randomness inherent in the community?
