I've watched Google become less and less reliant on the ODP data. Today, it's all about Wiki.
Heck, even the discussions around here about ODP have continued to decline which I'm sure the ODP Editors appreciate as we're all a bit frustrated with the continued whining.
I say just move on and accept the things you cannot change. I foresee one particular directory inching closer and closer to ODP status. It will probably be another year or so, but it will most likely be the new ODP. ;)
Sell the darn thing. Get out now while they can make a little profit. Let someone else turn it around and make it the powerhouse that it should be.
