We recently launched a new version of <a href="http://www.myrudis.com" >.  It's a new take on the freelance marketplace model with key, important differences.  Freelancers, keep 100% of your income.  Most importantly, SPAM issues are obliterated.  You'll no longer drown in bids from individuals who didn't even read the project description.  Employers, find freelancers who are really serious about the gig.
Hopefully that is acceptable for this thread.  I realize it's some self-promotion, but really relevant.
