I read;
Dominic Deegan - Great comic, wish he would go back to his old punning ways though.
Ctrl Alt Del - Definitely has its moments, if he keeps doing these 'make your own adventure' arcs it will be more entertaining for me.
Penny Arcade - Might stop reading this one, its gotten pretty terrible lately. Seems to have dropped most of the humour to instead be a commentary.
XKCD - Just found this one the other day. Perfect for me, contains geek jokes and absurdity in volumes.
Megatokyo - Stopped being funny after Rodney left but still fairly compelling.
8 Bit Theatre - Currently one of my favourites, the characters are highly stereotyped and funny.
Cyanide and Happiness - Also has its moments, a lot of its trash though.
VGCats - I always forget this one because the author always forgets to update =P
