Which tags do you think should be renamed? Let's add here tag-rename requests as answers. We can vote up answers to indicate that we agree with that tag-rename request and use the comments to discuss the request.
Unless there is a discussion about a tag-rename, anyone can go ahead to change the tags after some time and upvotes. This to prevent that somebody just retags everything when a request comes, now matter what the others think... When we get moderators this task will shift to them.
Please all take a look now (and vote) and suggest more tag renames if you have.
