Careercows and reddit lolcows like Pizzacake are almost certainly 95-105 IQ.
JF Garapey and Liquid Chris for example are probably two standard deviations above the mean, especially JF since he is both a self taught programmer (one good enough to do freelance work) and a neurosurgeon. 130-150 IQ imo.
I find programmer lolcows (Pirate Software, Yandere Dev, Terry Davis) to be the most interesting, since you can get an insight into how they think via what patterns they use in their code. Yandere Dev has the bare minimum ability to create something functional that imitates a game in Unity, and his code reveals that he isn't good at making abstract and reusable patterns, something that you should learn how to do through experience if you want to be a programmer. Pirate software isn't much better; he never goes beyond basic data structures and most likely couldn't explain what a pointer or linked list is even if you put a gun to his head. I estimate Yandere Dev to be maybe 105IQ and Pirate Software to be 110.
Meanwhile Terry has mastery over multiple different programming domains, with many things he makes (e.g his terminal emulator supporting inline images) adding new and often genius features not found in ordinary software. He could have been another Kernigan if he had the proper support. He probably has an IQ of 150 or higher.
