I would do a reverse treebang for hockey rps! A lot of the hockey rps fandom I know of gathers around individual journals or tumblrs, which is frustrating because you can never know about all of them and yet people will do things like post fic in the comments to a post and then never report it to an archive.

On DW there is theyretotallypucking but it isn't very active, though it does have a great master list to primers for teams, pairings, and players. On LJ there is also 2mins4slashing which has fic only, but is a good place to read a lot of older stuff from before AO3 became big.

The only solution I've found has been to follow a few select tumblrs and read the awkward conversations that occur on tumblr and mostly not feel involved until I post a story, then a couple days later I no longer feel involved because there's no conversation happening.
