You might notice that I'm pretty big on using web 2.0 for library or library-esque purposes. That all started with this:
kohafive: Review: The Time Traveler's Wife / Audrey Niffenegger
This link takes you to a review I did for a blogger application linked to a Koha open source integrated library system (the online library catalog for non-librarians.) This was set up for a Library Technologies class project during my MLS studies. (Though the review itself was written for another course.) Basically we had a blogger where we posted youtube video reviews/trailers, our own reviews, or other reviews and then we linked it back to the "url" line in the marc record. It wasn't always the prettiest but it worked. Also nice was the fact that we could link the blog to the item in the record and so doubling the usefulness of the Library 2.0 technology. I really liked the Liblime Koha platform, it was really librarian and patron friendly, and fairly intuitive. Blogspot has always been super-user friendly and easy to make professional-looking without devoting an insane amount of time to getting it running smoothly. I love my LibraryThing applications and how easy it was to link LT back to Blogspot and vice versa. That is probably one of my favorite things about the web and readers' advisory: once a good resource is found they often have a web (2.0) of other resources that are as useful and accessible.
