Startup Idea: Hacker News reading recs. I use Goodreads now, but it doesn't really solve the problem recommending books to me that people like myself enjoy. It shows me what my mom and other people I know read, which is interesting, but most of the time not particularly relevant to my interests/career. If there was a review site that essentially did what this thread does--let people with common interests recommend books to each other, I'd look there first when I was choosing what to read next.
