I only see it once in a while, but would like to ensure an elimination trend continues. Back in this Meta post it was suggested and agreed to the "year tag" should be eliminated. I do not believe having a year in the tags helps with the meta discovery of any given vehicle and ultimately wastes one of the five meta tag slots. If you see a tag being used as such, I'd recommend editing the posts (or tags) and eliminating the tag from the post altogether. This will help to keep the tags clean as well as discourage others from using/making year tags.
By year tag, I mean 2007 or 1996. In and of itself is a very non-descriptive tag and has been fleshed out before, it fairly useless. The reason I posted this in Meta is I see it every once in a while, so would like to reinforce the guideline which was setup at the beginning of the Beta for Mech.SE. Thanks.
