I never got much further than cataloging the dozen-or-so Henry Reed books on my LibraryThing bookshelf. LibraryThing, however, continues to grow.
They now have a part-time librarian, as well as a second blog: Thing-ology.
Thing-ology is intended as LibraryThing's "ideas blog": "the place where we'll talk about the meanings, methods, and debate around LibraryThing and its features." MetaLibraryThing! Sweeet. Whereas the original LibraryThing blog remains the spot for announcements of new features, plans, and news.
Check out the announcement of Subject Headings (re-)added to LibraryThing, and then the ideas behind the new feature.
