I continue to use eBay, but only for obscure collectibles and art that can't be found anywhere else. They're still irreplaceable in that respect.

Still, it's hard to imagine why they think spamming themselves with fixed-price auctions is going to be beneficial. If anything, it hurts them by drowning out traditional auctions. Fraud and flaky sellers are too much of a problem on eBay to use them for any item I can find elsewhere.
