I'm a big fan of Ken White (Popehat), his twitter feed is snarky and informative.
He has a new podcast on first amendment issues that is really well done.
I like him too. Just be cautious - he's a contributing editor at Reason, which is heavily funded by the Koches and tends to follow their agenda. I wish we had decent smart right-wing voices that weren't co-opted by money from billionaires, but they're pretty few and far between.
Ken White is close to that but the Reason and Fox connections taint him a bit.
Edit: after looking into it he's only got three articles at Reason and it looks like 'contributing editor' is an overblown title. Phew. I want to like him and think he's fair.
I'm a conventional statist liberal, find a lot of libertarian thought amoral, and don't like Reason at all. Your comment is dumb, and didn't add anything to the discussion. As Dan is constantly telling people here: please don't pull conversations into ideological tangents.
Wikipedia is highly connected. Even pretty darn different things often seem to have only three degrees of separation. For example, here's Ramesses II to Ankylosaurus in three:
I don't know if this is legit. The Lion Express node only connects to a couple of Wikipedia's generic help pages, which I'm pretty sure don't link back to Lion Express.
