Here are some library 2.0 ideas that other libraries are trying that I think are promising...
University of Illinois Undergraduate Library has a page both on MySpace and Facebook. They don't advertise their page because that wouldn't be "cool" but they have already gotten over 400 friends without advertising. On the page there is a blog and a search box for books and articles from the library. So, they can actually get to the library catalog/databases right from MySpace.

I also saw that Michigan State University Library created a search box to go with a personalized Google page which allows users to search the catalog/databases directly from their personalized Google page.
Even better, University of Illinois created their own search bar that works with either Firefox or Internet Explorer. It allows you to search departmental library websites, ask a Librarian, library's catalog, Online Research, the campus phonebook and Google:

I came across some of these ideas on David Lee King's blog.
Do you see anything here we might try at LCC?
