I've been visiting LibriVox a couple times a year, to grab books for long trips, for years. The site was usable but browsing and searching was always a pain. Using the new site is great, though finding audiobooks (M4B files) is still kind of a pain. Just about everything else is an improvement though (it would be nice if the genre(s) listed on a books detail page linked to that genre's list). I'm sure a lot of people are happy with this change.
