Just recieved the following email from Stack Exchange, and wanted to know if you guys think we should participate:
Last year, on our Gaming site, we hosted an event called Hat Dash, where users earned "hats" for their gravatars by completing certain tasks (analogous to badges). Certain actions would trigger the user receiving a hat, which their gravatar could then "wear".
For example, editing a post would yield an editor-themed hat (fedora with pen) to the editor. Examples:
This year, we're expanding the promotion to all sites which choose to participate, and redesigning the hat selection to be more appropriate to the entire network (no severed Wampa heads). Some of it is holiday-themed, some of it is a bit silly, and all of it is (hopefully) fun!
Note: Users who don't want to see the hats will be able to opt-out by clicking an "I hate hats" link.
