I'm always searching for ways learn more. I know a lot of smart people working on interesting projects, however it is often difficult to keep up with what others are working on. This past June I organized lightning talk presentations for my company. We had ten 5-minute presentations on various topics that we video taped and posted to our internal SharePoint site. I think it worked out great. Five minutes is just enough time to make a point or introduce a topic to an audience without boring them if they are not interested. If they are interested they can always followup afterwards to find out more. Lightning talks typically take place at conferences and give an opportunity for attendees to present to the larger audience, however I see no reason not to use the format inside your company as well.
I'm looking forward to our next series of lightning talk presentations tomorrow. I will be presenting on Cloud Computing in the Government.
