Yeah, but even there, he hasn't posted since August :( nowadays I think the only regular public activity is his participation in the podcast All the President's Lawyers - besides @Popehat on Twitter, of course.
Probably a matter of personal preference, but if you're not a fan of low-quality, intellectually dishonest shitposting in your feed, I'd avoid @Popehat on Twitter. I enjoy his columns and blog posts, but Twitter does weird things to some people's brains.
OTOH, my tolerance for that stuff is extremely low, so the SNR may suit someone else.
