On Let's clean up some meta tags there is a list of tags that look as meta-tags but after 6 years they are still "alive" (tags with
<s></s> were not included):
- filter - Can't possibly work as the only tag on a question. I see it used for gmail (it should be gmail-filters), google-spreadsheets, yahooemail (which should be yahoo-mail), youtube comments. This also seems to run afoul of the second point above (it means different things to different people).
- photos - This can't possibly work as the only tag on a question. It needs to be paired with a web app. On the first page of questions I see facebook, google-plus, instagram, twitter, gmail, dropbox. facebook-photos and google-plus-photos exist, at least.
- url - Again, this has no context without the existence of other tags. questions or network protocol curiosity that should also be closed.
Could we add to their tag excerpt DO NOT USE THIS TAG and a link to the above question in the tag wiki?
DO NOT USE THIS TAG : Uniform Resource Locator or Universal Resource Locator - a specific character string that constitutes a reference to an Internet resource.
