List Sites Created

Allow people to add sites that they've created to their profile along with details like hosting, type of site, colour scheme, etc.
Then people can get a list of sites close to what they're going to make for inspiration.
Also, that'll allow people to look at sites and find appropriate hosting for a site they're going to make by looking at similar sites and where they're hosted. Then create a link to that hosting provider and if you so wish, make that an affiliate link and make a few bucks.
I created a site a while back that did all of this, but I'm s*** at promotion and it died a horrible death. I stand by the idea though.
