Strangely adolescent behavior from these two Web giants. Google decides to throw a party at eBay Live, the online marketplace?? annual memberfest, protesting eBay?? (admittedly hard-to-justify) ban of Google Checkout. So eBay pulls its search ads from Google (and that?? lots of ads). Google, attempting to regain the high ground, or at least get the ads back backs down and cancels the event. Next move: eBay. And I bet it?? not a permanent departure from Google. After all, eBay drives a lot of traffic to its merchants by buying all those Google ads, and they won?? be happy to find suddenly that the buyers aren?? coming. Yeesh.
