I don't mean music videos or a silly cat jumping into a box--I mean youtube channels that post original content. Maybe recommend some channels or talk about some of your favorite videos. Some personal favorite channels of mine include: VSauce--which intersperses neato science factoid videos with geeky/cool things around the internet. Puddin'--(which I won't link to on account of being completely NSFW)is a "live action single panel comic strip" about one man trying to enjoy his snack break at work while constantly being interrupted by his often vulgar, totally disgusting, and constantly inappropriate coworker. Stars Eddie Pepitone and Matt Oswalt(along with some surprising guest stars). Periodic Table of Videos--The University of Nottingham produces this series of videos featuring an element of the periodic table in most videos. In the other videos they do chemistry experiments which usually end up in something exploding. Geek and Sundry--Features a variety of videos, M-F, including the Flog(Felicia Day's vlog), Tabletop(a group of sort of famous people play a tabletop game hosted by Will Wheaton), and my favorite: Tuesday Night Hangouts: The Story Board(a panel of authors talk about things related to writing). Anyway, I could go on(Daily Grace, Continue?, Community Channel...), but I'll stop there. Do you have any favorite Youtube channels?
