Oh man somebody made a good web-based public social tagging personal library catalog that interfaces with Amazon AND the Library of Congress. Man! I’m not going to get anything done today.

In other news to make my friends geek out, LEGO has released software that will let you build your own virtual models and then buy exactly the pieces you need to make them in real life. Brilliantly obvious. The software is free, but disappointingly closed-source, and only for Mac and “PC” (by which they mean Windows). Opening that shit up could generate a pretty incredible building-hacking community.
