I don't know, it would generally be nicer to know I'm working with someone who can tell where I'm doing better or worse than the average developer. The offer to work for free doesn't make a ton of sense unless you can get some meaningful feedback.

In that spirit, feel free to drop me a line as well. My actual experience is in shell scripting, Perl, PHP, MySQL, and Coldfusion with MS SQL, but I like Python, C++, and would love to pick up some other stuff. Contact info in profile.
