I don't actually know on that one, a few months ago I would have probably had one, more recently I just have lots of channels I enjoy watching. I think Richard Lewis is hilarious (/RLewisReports) also very informative from an eSports perspective. I adore Day[9]s outlook on life (/day9tv) and he's always made me feel better. Just for the sake of having a third I'll throw RoosterTeeth as a company in there.
God I've had too many YouTube channels to remember that, on my very first channel probably like Charlieissocoollike or someone like that, on my current channel? Errr I think it was Jesse Cox or TotalBiscuit, I know they were the first two.
