Listdump

I had a look at Listdump, a community generated list site:
http://www.listdump.com/
I'll let Listdump describe itself for you:
Listdump is a community list generator based on the simple fact that everybody loves a good list. Create a list of the best how-to sites, or download sites ... Hey, you can even create a list of your personal life goals and let others help you prioritize them by voting. Anyone who's a registered member can contribute to a list, tag, comment or vote on a list. The top rated lists show up on the front page. There is also a page for new lists.
Create Lists

Create a customized list
Add links to any item within any list
Put in your 2 cents and help tag a list
Keep track of your favorite lists

I liked the front page design: you can see what is most popular, most recent at a glance. There is also a tag cloud on this page, a useful browsing point. Each entry is also well-defined. You have an image (for aesthetics), title, and vital statistics. Listdump was easy to use.

What could a library do with this?
So much. Users can compile their own lists of resources. Others can rate these lists. An informal way of keeping track on what is being used, what is most popular, what information resources need developing.
The social aspects could also make it appealing to students: they could also rate other things on campus: the cafeteria, parking spaces etc.
