Interesting idea. As a somewhat non-traditional CS student, I could definitely see this as a tool I would have turned to when I was starting out.

One of the most frustrating aspects of studying CS is that my professors would come up with problem sets and assignments on their own and their solution would require something not found in online resources. There were quite a few times where I could only find tangentially related information in very obscure places. Hopefully your service can address this issue effectively.

Also, it seems like the folks here on hn aren't your target demographic so the pain may not resonate here, but i think it exists in a deep way, none the less.
