ragegamingvideos (back in late alpha and early beta when he made good minecraft videos, he doesn't make minecraft at all now because it got 'boring')
I personally like iPodmail, AntVenom, and CaptainSparklez. My friend also knows iPodmail in real life so that's kind of interesting. I mostly like short and to the point videos but I also do like longer videos like the ones from bluexephos.
Yeah I'm a Yogscast fan too, and I also like CaptainSparkles when he did Skyblock (not related to my user name in any way). Don't watch too much minecraft youtube stuff, but Simon and Lewis are dead funny..."Sod that; "Honeydew spawns some 46""
