Real life use of the SQS service

I think I might be stuck in too much of a traditional enterprise mind set. I was wondering who would use Amazon's message queue service, arguing that it's a B2B enterprise style offering, yet surely an enterprise would host its own queues?
Turns out I need to be thinking a bit more web 2.0.
Here's a post from the Gravatar blog that gives some insight into their infrastructure (along with some technical difficulties they've been having recently).
(In case you haven't come across Gravatar before, it's a site that allows you to upload an image (avatar) that you can assign to your email address. Blog sites can then link to the image in their comments. Nice, but I don't know how they pay their leccy bills.)
This is a nice decoupling of the image serving servers, the safely backed up images and the image upload process. It may not be B2B, but it's an enterprise scale system and it's "publicly" hosted.
