The former CIO of AT&T Wireless (Chris Corrado) is going to replace eBay's CTO (Marty Abbott). I don't know much about Marty, but I think he has probably done a good job. I can't recall any major outages in eBay since he started in 1999 (there definitely were some before then). And he probably had a big say in eBay dropping Passport, which is a good thing.
Hopefully Chris will do as good of a job as Marty.
