I'm on my second try entering content for a tag excerpt on this site. Who is rejecting these, and how can I find out why? My first try must have been really bad for someone to decide that having something is worse than having nothing! I've never had a tag edit rejected on any other site.
Have a look here: https://engineering.stackexchange.com/review/suggested-edits/123
Robert Cartaino rejected the edit and stated:
Simply defining what a [tag] is rarely helps those using it unless the tag's name itself is ambiguous. Excerpts should describe why and when a tag should be used.
Which is pretty standard grounds for rejecting a tag edit within SE. There's some Meta.SE guidance to that effect.
And I found that by going to your suggestions activity page
Looking at your other suggested edits, I would venture a guess that they'll be rejected too. Excerpts should provide guidance on when to use a particular tag as well as explaining what the tag represents.
