Last time I did it manually, but I've got a much better source now.

http://redditlist.com/all?page=2

Including NSFW subreddits, TRP is #198 for recent users.

/r/Relationships is #95

/r/TwoXChromosomes is #102 (TrollX is 15, even as a default subreddit it loses out to a non-default meme subbreddit)

/r/Childfree is #123 (seems relevant to RP interests, but I haven't checked it out yet)

/r/Sex is #154

/r/AskMen is #236 (This is the second most influential male focused subreddit, after TRP, which gives us a much better picture of the influence we have)

/r/AskWomen is #240

/r/MensRights is #254 (I'm a bit surprised by this, expected it to be lower, I guess the simultaneous users just never gets that high there)

/r/everymanshouldknow is #446 (heh)

/r/Furry is #552 (just in case I get tired of looking for /r/Feminism, to show that there's more furries than active feminists)

/r/TheBluePill is #590

/r/relationship_advice is #624 (I wonder if this is a less shitty version of relationships or if it's just redundant)

/r/Feminism is #752

/r/OneY is somewhere past #1500, showing how little of a fuck men give to an effort to build positive masculinity that doesn't attack feminism. so is /r/DarkEnlightenment and /r/PurplePillDebate
