Yahoo Photos, Biggest Web 2.0 Site Ever?

Yahoo Photos is now out of beta–so it seems that web 2.0 is really and truly coming to the masses. Yahoo is the biggest photo-sharing service out there, with 30 million unique monthly visitors worldwide, according to comScore*, and more than 2 billion hosted images, according to the company. And Yahoo Photos (not to be confused with Flickr), has an impressive array of features–drag and drop with lassoing, free unlimited storage, high-res downloads, all the social sharing stuff.
