I have some extra time today, so I've been adding tag wikis for tags that simply don't have any. All of them have been approved overall, but one received a reject vote: word-hero excerpt. The rejection message is "This edit does not follow any of our tag wiki guidelines and is unlikely to help instruct future visitors in the appropriate use of the tag." The excerpt is "[WordHero] is a word puzzle game for Android."
I went to the link mentioned and I find five guidelines which I've supposedly violated, but I don't see it.
Keep it short! My excerpt does not attempt to do anything other than identify the relevant game. It's well under the 500 character limit. It's probably less than 50 characters.
"Avoid generically defining the concept behind a tag, unless it is highly specialized." This is a game title of a game obscure enough to only have a few questions in it. If that's not highly specialized, what is? I also contrast that with tag wiki excerpts like that for Diablo 3, which defines that much more popular game far more generically. Is there really anyone who does not realize that Diablo 3 is a sequel to Diablo 2? Or is that tag wiki excerpt wrong too?
"Concentrate on what a tag means to your community." It identifies the particular game. What more is there to say?
"Provide basic guidance on when to use the tag." What more is needed than a description of the game? Again, compare it to the Diablo 3 excerpt. Isn't it implicit that you should use the tag on questions about the game and should not use it on questions not about the game? Do we really need to spell that out in every excerpt? That seems far more relevant on tags about platforms or the audio tag. People don't need to know what an Xbox is -- they need to know that they only need that tag if their question regards something that is true in the Xbox version but not the PS3 version.
"Some tags are common knowledge." Sure, but this one isn't. Like #2, this guideline seems irrelevant to this particular tag.
It's not clear to me how I violated any of these guidelines, much less all of them. That excerpt says that the tag is for a particular game and provides a little description of the game (it's not the first person shooter [WordHero]). Am I missing something?
