Is there any practical way/reason to use WCF on a small website? [View all]

I just got a new job (yay!) and it starts in 3 weeks, so I wanted to get more experience using WCF before I walk in the door.

I have a few website I've created on my own time, including a gallery type site, and an eCommerce type site. But I can't think of any way WCF could be useful. Is there any plugin or something that requires the use of WCF? Say, a comments component that might use WCF, or a way to grab email contacts, or anything that uses WCF outside of a B2B setting?

If not, I guess I can just have my two sites talk to one another using WFC... I guess that might work....
