Tweet if you can hear me

Conference attendees are often advised to turn off their cell phones or Blackberries as a courtesy to speakers at various industry events, but attendees of the Internet Retailer show in Boston earlier this week were encouraged to Twitter throughout the show.

After I updated Chain Store Age's Twitter status during the session, "To socialize or not to socialize," a representative from a technology company I've profiled in the past saw my message and tweeted me back. "Is that Samantha?"

Although I couldn't find them in the crowded room, it's funny how the Web can make big spaces feel so much smaller sometimes.
