I got a job online once -- back when Usenet was king and the web was young. I posted on misc.jobs.resumes. That's how I ended up in the Philadelphia area, in fact.
The web job sites suck rocks. 99% of the "jobs" seem to be from recruiters just trolling for resumes without any actual jobs. The rest of the jobs are usually no good. As with the paper want ads, only the lousy jobs end up being advertised.
BTW, contrary to popular belief (and as SteveDallas points out), companies HATE it when they get 1000s of resumes for each position. Remember, they've got to wade through them all. Much better to get just a few good applicants than thousands.
I'm not worried about the top 10% thing. In any job I'm interested in, I'm #1 of all the applicants of course
