I looked at those a while ago, and was happiest with Craigslist,
because they seem to have the most 'real' jobs at the time, rather
than the sort of thing you'd see along the lines of:
"20+ years Java experienced needed. .Net Ruby Perl Python Tcl Erlang
Haskell SGML HTML SQL also a plus. Ideal candidate also has knowledge
of many other industry buzzwords"
