Ask HN: Smart/clever ways to get code reviews while teaching yourself to code?

Hi everyone. I'm working on strengthening my programming skills by working on fun projects and going through books like "Exercises for Programmers". I was wondering though, since I don't have any teachers or mentors right now, what are some great ways to get feedback on my code and problem solving techniques? I know some great ways are to post questions on sites like Stackoverflow and niche forums, as well as keeping a blog, but are there any other approaches? I figure the best way though might be to just get an entry level job down the line. Cheers.
