I never used the word hurt, it was negative emotions I used - not the same
I think with so many options out there wagglepop is just another one to add to the list. I don't think any of them are going to get the sellers if the buyers are spread out all over the place.
Speciality sites, free stores that can be marketed like your own website or even having your own site is what will work best in the long run.
Stop expecting someone else to bring you customers, go out there and get them. Look for directories to get listed on, join yahoo groups that are set up for selling, get out and network with other sellers, get your name, your product and your link out there.
This is the way to go, putting trust, time and effort into another auction site will not be the answer.
But hey that's just my thoughts
