Don't really have any real ones, but recently, I've been having a field day with mac3079b's Beatles videos. Great tastes/selection, really cool photos/effects, some really cool rare stuff, and the sound quality is so much better than anything I've been able to get my hands on (I even found myself getting really into some of the songs I didn't previously like)
Probably my favorite is Justicar. He's a former police officer turned mathematician gay athiest logician. Naturally, he makes some pretty particular logical arguments against whomever argues back, but I actually appreciate that a lot. He changed my opinion on gun control simply by approaching it from an angle I never thought of.
I like thunderf00t. His science videos are good, and while his videos beating up creationists are a little bit of choosing easy targets, the more strident stuff is actually interesting. Actually, most of all I like his arguments in favor of free speech and in promotion of science.
