During her interview on CNBC, Yahoo CEO Carol Bartz trashed Facebook when asked, “Why isn’t it [Yahoo] as hot as Facebook?”

Her answer? “Remind me what’s their revenue.” It’s a cute response, but we doubt Bartz has been paying attention to the fast growing social network. Just today came news that Facebook may score as much as $1-$1.1 billion in projected annual revenue for 2010. That’s up from $650M-$700M that industry insiders projected for 2009.
