There's a new page on the code4lib website for the lightning talks.
Lightning talks are 5 minute talks where any attendee can get up and
talk about something of their choosing. I checked with the
authorities and can say with very little certainty that doing
lightning talks will have no negative effect on your 15 minutes of
fame...that might be the cold medicine talking though.
Anyhow, If you are interested in doing one (or more) please add your
name/topic to the list. There will be an official sign up sheet the
day of the talks, so you can wait till then too. There are only two
weeks to go before Corvallis so it might be a good time to organize
your 3 slides :-)
