Sadly, Hockey RPF is incredibly scattered. AO3 is the only really consistent place to find it. There are comms at hardtothenet, home_ice and hockeypedia, but only the last of those three is particularly active right now. (There's also a fairly active anonmeme hockeyrpfanon, but I don't know how you feel about those.) There are lots of people on twitter and tumblr who talk about it, but it's hard to find them among all the general hockey fan stuff, plus a lot of the rpf twitters are locked. I can give you some actual names, if you want, but it'll inevitably be a pretty random list, and someone else would probably have a different one.
