The Flippa blog has been bought back from the dead with this post explaining that you can now negotiate a with buyers if a site does not sell due to a reserve that was not met during the auction. If only someone had thought of this previously!
Seriously, why would anyone use this? Once the auction is over, the requirement to give Flippa a cut of the sales price is gone, so buyers and sellers would be much better off negotiating via email or Skype or any of the other methods that were available before Flippa created this tool to try and hold on to a little more revenue.
I do like Andrew's little jab at sellers who have an unrealistic reserve price.
