I found the F Plus through Zarla and Internet Computer, actually. I'd been following Zarla's art and such for years, and she happened to link Internet Computer when Portaxx's animation became public. It happened to hit all my giggle spots -- funny voices, funny premise, enthusiastic reading of typos -- I had to have more.
So I followed links through Portaxx's post and listened to Hans von Hozel, and laughed through the whole episode. Now, I won't say I was fully hooked then, but I will say I kept returning to it and decided I wanted more. So I went back to Portaxx's info post about the podcast which recommended some episodes, and I scrolled through looking for something not too gross. "Reno iz Drest in a Kostoom" was my second episode -- hey, I figured, I'm a roleplayer myself, I'm well-acquainted with some of the awful Mary Sues and Gary Stus that populate the field.
I was not prepared. But still I laughed, and wanted more. Which surprised me. I'm not usually the atrocity tourism type.
So I went, "well, okay, let's try a more hardcore episode from the list, see if I can stomach that." Zarla's stick-figure animation about the guy bursting into a barber shop looking for Supernatural fanfic had come out by then, so I craved context.
I stomached it handily -- having been exposed to some of the awful stuff that populates kink memes out of a sense of morbid curiosity -- and have been hooked on the podcast ever since. X3; There are only two or three episodes at this point that I DON'T want to listen to again at some point (monkey moms and dickbugs, with a side of fuckdolls), and I think I've listened to them all at least once. They make great background noise while I play games -- it makes me feel like I have a bunch of friends over reading and laughing at stupid shit, which is always fun. Plus, a good number of episodes serve as public safety announcements, in my book; if you hear or see anyone who reminds you of an F Plus subject, WALK AWAY. :P
I have learned not to listen to new episodes while driving, though. I had an incident somewhat like Kumquat's with the Sherlock episode, though I was in a car. I vaguely remember going "dog cocks WHAT -- WOLF PACKS DO NOT WORK THAT WAY" and nearly driving into a cornfield due to chagrin and laughter. Whoops. :B
