I am not following youtubers that much any more, but my favourite youtube entertainers would be Hannah from the Yogscast and Lisa Foiles, but I've been watching others on and off as well such as Tobuscus, TotalBiscuit, Pewdiepie and Jesse Cox (OMFGCata). A while ago, I stumbled across AuzzieGamer's (I believe that was the channel's name, but I might be wrong) videos, however he is not that active on youtube, so I finally drifted away from that.
