Tags need a regular cleanup. There was a number of questions on particular tags recently — but (while proposals for some really major changes should, perhaps, be posted as separate questions) maybe a separate question for each case is too much.
In the past we used Tag merging and synonyms thread — but it grew too cluttered to be of much use.
Rules of the game are basically the same:
- post your suggestion as an answer here if use see
- a particularly bad tag (rule of thumb from the previous thread: «roughly speaking ... if I can't imagine a person classifying a tag as either interesting or ignored, I'm getting rid of it»),
- a tag that should be a synonym of an existing one,
- a tag that used for two or more completely unrelated things;
- upvote/downvote/comment as your agree/disagree with suggestions;
- wait a day or two before implementing suggestion;
- when retagging questions by hand please keep your rate down to a few posts a day, so not to flood the main page.
