User blog:The Nobodies Rules/What makes a certain AU a popular one?

Not that I am annoyed at the fact that there are so many AU's within the fandom (In fact, I love it!), but just like how you can't just add a certian movie/series/character into this wiki unless they have been used and known in alot of fanfic/fanart, I am wondering when can you decide which AU is well known enough to add to this wiki?

There are some AU's that I see, that barely has anything written within the page and I get confused because I would have thought that since someone added a page for that AU, it should be well known enough for others to add and edit into it and know what the AU consist of.

...Am I making any sense? Sorry if I am not, I am just curious is all but yea.

What are the criteria that makes a AU popular enough for one to be allowed to add into this wiki/fandom?
