I sit at work and hit "Random Article" all day. I edit what I think needs editing, and tag what I think needs tagging. I don't bother with long discussions or arguments. If someone reverts an edit I made, that does not concern me. If someone does take issue, I will at least explain my motives. Otherwise, I just keep hitting "Random Article".
