How Can Yahoo Afford To Give Flickr Users 1TB Free Cloud Storage?

I grant that I could be wrong as I'm not a hardcore Flickr user and don't have access to the statistics that Yahoo has on usage patterns. However, I'd bet that the overwhelming majority of people that would use Flickr won't come close to using anywhere near 1 TB of storage anytime soon.

More than anything, I think their announcement is really just a smart marketing gimmick that gets them on peoples' radar and gives them nerd credibility without doing much extra.
