How Tech Savvy Is "30 Rock's" Katrina Bowden? Last week on "30 Rock," Jack asked Cerie for tech advice: he wanted to know how to "reply all" to an e-mail. She looked at him like he had three heads. But in real life, Katrina Bowden, who plays "30 Rock's" perpetually clueless assistant, said she's not at all tech savvy. "I learn a little bit here and there, but I'm definitely not good at figuring everything out," she told ABCNews.com Wednesday at a dinner honoring celebrity hairstylist Beth Minardi. My fiance [musician Benjamin Jorgensen] is the one who does that for me. I guess because I have someone who's good at doing that stuff, I just throw my hands up in the air. She's got her favorite social network ("Twitter is the thing I go on the most") and fashion inspiration site ("InStyle.com always has great looks"), but with "30 Rock" winding down, Bowden's spending most of her time buried in scripts and wondering how it's all going to work out. I really hope that everything wraps up for everyone in the show, that everyone gets an ending. It's going to be hard to do after seven years, but I'm excited to read the last script.
