I'd say the same principle applies to LCF and Kiwifarms, to a lesser extent. I'm not sure how many anons on LCF have accounts here, since the anonymity is part of the appeal of image boards and something they dislike about more conventional forums, but people definitely lurk, and there's an exchange of information between the two sites. Documentation of Fanny Perret is an example of that (a real shame that LCF went down shortly after her discord logs were archived.) What I will say as someone who uses both is that Kiwifarms has better OPs and a better search function, but Lolcow is better for archival reading. KF has a serious problem with people parachuting into featured threads to make the joke that's already been said twenty times, or with people going completely off-topic in a thread for days on end. It makes for some good locally-sourced cows, but it sucks if you've got a backlog of shit to read about a cow you and have to wade through the kind of non-contribution posts that usually warrant bans on LCF.
That said, Lolcow's admins are consistently mediocre, and it's been a point of contention for years now. Kiwifarms really benefits from having an ooperator as autistically dedicated as Nool, and I'm not just saying that to blow smoke up his ass. Most independently-run sites like this get shuffled between a bunch of different lead admins, just because of the nature of it.
