"...he doesn't get as many comments as popular bloggers like <list of PUA bloggers>" [...] Admittedly, I don't actually recognise all those names.

Most of those aren't PUA bloggers, actually, although they do recognizably share a certain cluster of perspectives. Megan McArdle is a libertarianish policy blogger with the Atlantic. Vox Day is mainly a spec-fic blogger, lately notorious for association with what SSC readers might recognize as l'affaire du reproductively viable worker ants. Steve Sailer is hard for me to classify, but in this crowd he'd probably be best known for what I'll politely describe as contrarian views on race.

If I had to guess, I'd say they're probably just the most famous bloggers that a specific right-of-center geek happened to have read recently.
