I have this good friend, Michael. He's geeky and nerdy in the best ways. He's constantly introducing me to new things to like, like Bee & Puppycat (a very strange and wonderful web cartoon), the game Portal, and lately certain seasons of Dr. Who.
The best thing he's introduced me to though is the concept that there is no such thing as a "guilty pleasure." It's totally okay (and in fact great) to like things just because you like them , and no fandom opinion for or against something has any bearing on that feeling.
I know! When I say it out loud, my overwhelming feeling is, "Um, duh! OF COURSE! " But you'd be amazed how pervasive that feeling of "people will think this is stupid" can be. I'm grateful that I know better and can get over myself about it.
I've got plenty of esoteric or downright odd things I love. I love Alan Watts lectures. I also love cat macros. I even make my own, from pictures of my own cats, or ones I find that strike me funny.
Dig that. Guilt free!
