Alright, now that this site's existence appears to be secured, we could spend some time "cleaning it up".
How about we gather some duplicate tags in the answer and decide on whether they are really duplicates (through comments and up/downvoting)? Don't know how the second phase works, perhaps moderators know more about efficient retagging of questions (that doesn't involve manually editing every single question).
Can we please also be aggressive on down votes? If you dislike a tag-merge, dont just ignore that post. Downvote it.
