my mom uses lj and tumblr a lot because she's big on fanfic and fandoms, she was a bnf back in the days of e-mail lists (thankfully not a wanky bnf from what i can tell, but i don't really look into it just in case). she used to be mostly book fandoms but she's starting to get into jdramas and anime; i had to explain the concept of "moe" to her and that was about the weirdest conversation of my life.

my dad reads a lot of webcomics and tech blogs but doesn't chat or do much realtime interaction, so he tends to pick up on random memes and net-culture stuff but in a kind of adorably out-of-touch way. he discovered "the cake is a lie!" a while ago and still thinks it's hilarious, and i've never been able to bring myself to tell him how painfully oldmeme it is.
