What sowed the seed for me was at Otakon 11 and seeing the flood of troll cosplays and thinking 'this is a thing that a lot of people like, maybe I should check it'.
This thought goes on hold for maybe eight months until I started reading Homestuck in like February or March of this year. (Problem Sleuth was somewhere in there to get more background on the Huss's humor and whatnot)
I started readnig because I saw this flash <

On a slight tangent then I am proud to say I have traded 4chan for the much more pleasant company here at mspabooru :3
