I know, literally, nothing about ML. Why's it better for a beginner? Can you recommend any implementations in particular?

davidw above mentioned getting involved with open source - have you got any suggestions for how to get stuck in?

Thanks! :)

P.S. Do you think it's necessary to have a presence on the web, i.e. through a blog, in order to make connections with other kindly programmers? I'm also thinking that as I'm starting from scratch, I could record my progress and potentially help other baby hackers.
