Looking for feedback on a new free service

We just launched a free beta service that simplifies the process of doing Boolean queries to find resumes/profiles online. You can still use Boolean operators, but we automate the more mundane tasks of finding people online (e.g., site-specific search is as easy as toggling the sites you'd like to search, etc.). I'd love to get your feedback on this thread about the current service and any other enhancements that you think would make it more valuable.

Thanks for your thoughts.
