LibraryThing is doing a Halloween Hunt - find the authors, books, tags, etc that the 'riddles' indicate - in the last 20 minutes or so I've found 9/15, although some of that is because I have an idea of how these hunts work. But they are at least a fun way to spend some time. Not sure if you need a login, but you can get one for free (and put up to 200 books in as well -- and set up a tinycat catalogue). ADD: if you get five of the pumpkins, you can upgrade to a lifetime membership. Which I think means you can put any number of books in. The mobile app (iOS and android) will scan barcodes to add books to your library.

Australia talks - how do you fit in with the views of the 54 000 Australians who took part in a national survey?
