I've always seen Yahoo as a "me too" company - the Carl's Jr of the online titans. If they've ever been the best at something they've never stayed there for long. The decline began when they decided search wasn't their core business and portals were the way to go. Who would want to work there? Even Microsoft are more innovative these days.

Having said all that, thanks for buying Viaweb off PG guys. At least some Yahoo cash went to good use...
