A few years ago I wrote a fast parser for OSM data. I know that using parsed data would soon become out of date, but I guess mvexel's server could handle it better. If you want me to export the whole world's contributors as CSV or SQLite, I'd be happy to help.

The tool is interesting for me because I'm looking for a job in NZ/Australia/Canada. I've had more success contacting people rather than sending job applications - most job listings require me to already have a visa. I think that collaborating on open-source projects is a good way to make industry contacts, demonstrate my skills, and also benefit the community.
