I recently signed up for Goodreads, a social networking sites for bookworms. Although I've seen it pop up occasionally over the years, I was never terribly interested since I've rarely obsessed about books for more than a few weeks at a time.
I finally joined up when I realized that I've gone about five months with voraciously reading everything in site, partly due to bookclub (which I'm terrible at attending even though I read 90% of the books) and the discovery of a few favorite bookstores in the LA and La Jolla areas.
Goodreads isn't for everyone but I'm enjoying it right now. And since one of my goals for 2013 is to read 26 books this year (which I am way ahead of schedule for), it seems like a fun way to do so and get other book recommendations.
