Nice idea. Coding interviews are a true pain for so many hackers. I like the approach of connecting similar people to help each other improve. That makes a lot of sense, especially for geeks.

But that also seems somewhat troubling... especially because I'd normally inexperienced or first time job seekers using the site. Would that be like the blind leading the blind in a sense? There is a lot to learn to turn into a good interviewer.

Even if you don't test someone's ability, having them declare if they are interested in conducting interviews or being mock interviewed would likely get a good separation and better experience for all.
