One of the most informative and inspiring web conferences is An Event Apart, which takes place several times a year in locations all around the country. This time it was Seattle's turn to host the conference on April 5-7, 2010.
While I did not attend in person, I've gathered a few links that helped me attend in absentia:

First, there's A Feed Apart, which aggregates all tweets with appropriate hashtags into one updating stream. Depending on how talkative the crowd is, you'll get most of the major points of the presentation.

Luke Wroblewski, also a speaker at this event, maintains a decent collection of notes (also from past AEA conferences) on his blog.

Garrett Nafzinger provided a comprehensive set of notes on his blog, usablewebb.com

Andrew Philpott also gave us a nice set of notes starting with Day 1.

There's even an AEA Flickr photo pool.
