Today I discovered LibraryThing has added venues and events to their database. Users add their favourite bookstores, with links, and if you specify a location in your LT profile you can get a list of nearby bookstores, with ratings, and also any upcoming events in those stores.
Just go to www.librarything.com/local to see the results in action. You even get a Google map of the bookstore location.
All very web 2.0
I stuck Fantastic Planet and Dymocks Carousel in the database, since both stores have been kind to the Hal books. If you're on LT and have a fave local store, why not add them in too?
