Thanks for posting the article - it gives us some options to explore. My quick observations, since I have listed on a lot of auction sites over the years:

For me, the only site that actually delivered buyers has been eBay. Even big names like Amazon and Yahoo auctions failed to deliver bidders or buyers.

It's interesting that sites are adding so many sellers per week. The more important questions are (1) how many *buyers* are registering each week, and (2) what percentage of items are actually selling?

I intend to open accounts at several of these new auction sites, and I will report back on whether items that sell on eBay also end up selling on these other sites.
