Flickr is a must for libraries- I liked the Hennepin Library's "Bookspace" series, in which patrons submitted photos of themselves reading books. It's fun to look at pictures, and people who attend library events will feel more a part of the library if they see themselves on the libray website- in fact, they'll probably tell their friends and relatives to take a look, too. I really liked Westmont Public Library's idea of showing the new books, with the option to link directly back to the library catalog - I have to figure out how that's done- something involving objects I guess. Knowing how simple Flickr makes things, it's probably not too difficult. Also want to explore the Swan Online Catalog they are apparently using.
Podcasting is a bit harder- all the downloading and whatnot probably deters alot of novice users. The explanations are kind of wordy- all the sites needed clearer, simpler explanations, but Denver did a nice job. Their page is so friendly looking that it inspires trust in the user.
