I’ve seen this phenomenon at the last couple of FoxPro conferences: folks with laptops can be tuned in or way out of the presentation. At DevCon, I blogged the keynote live and made my one and only appearance on the Radio Top 100 blog list. OTOH, some folks tune out and miss the whole thing. Of course, they could do that with Solitaire, too. But now, with IM, they can join in a conversation… interesting. NY Times: In the Lecture Hall, a Geek Chorus. Mr. Aral discovered that he was not alone. The next day in the auditorium, which was outfitted with a wireless link to the Internet, a group of people booted up their laptops, opened their IM programs and spent the next three hours happily exchanging notes during the presentations.
