We have the Cattle Drive (java college), where small Java programs are evaluated and critiqued by seasoned Java developers. It's based on programs you write for certain problems chosen by the evaluators, though, not for submitting some arbitrary piece of code. You can find more information, as well as the problems you'd be working on, here. [ January 01, 2007: Message edited by: Ulf Dittmer ]
With respect to doing code reviews for anyone that wants to post code, I think it is a great idea and something that we have considered, but unfortunately it is too much work for a volunteer run site, and no one appears to want to pay for it in a general sense (The Cattle Drive is aimed more at structured learning).
I think code reviews are great for learning, so if you know a way for us to sell it to others, don't keep it to yourself!
Given the amount of time needed to do a PROPER code review you're not going to find QUALIFIED people willing to do it without some form of compensation (most likely monetary, though goods might be possible). If you don't you'll end up with people who mostly will do a poor job at it, either through lack of skills (having someone with 2 weeks' experience review code for someone with 1 week's experience) or lack of interest (just skimming over it because the reviewer really lacks the time to do it but promised he'd have it done by the end of the week). Neither situation is good, it will lead to people getting an incorrect impression about their code, either by thinking they made no mistakes or having things classed as mistakes that aren't by reviewers who don't understand the code they're supposed to be reviewing.
There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors

that's a different service, they're there to do your homework for you (at a price). Not dissimilar to sites selling book extracts and research papers for kids to turn in as their own, except the chances of the customer being caught at cheating might be lower as the variety of goods delivered is likely higher.

Thank you very much Veterans for explaining the practical problems involved in the idea of Code reviews.
