I'd love to create a "featured" site block that chooses a random child site in the network, and grabs info about it as pictured:
It seems easy enough to add a new field to the admin panel area user profiles, and I figured that child site admins could just enter a URL for the 125x125 image there. If the child site admin's bio info could be pulled, the value of the new profile field could be pulled as well, right?
Anyway, is there a plugin that will do this (or is anyone interested in creating one)? I have seen a WPMU featured blog widget floating around, but I want something that automatically displays a new blog (site) each time a page refreshes, and that plugin requires the network admin to input a blog ID number to display.
