At the DMA this past week in San Francisco, I was finally able to use the Fast Society iPhone app that I installed a few weeks back.
Fast Society calls itself an “Instant, private, short-term mobile group chat”. Since I was traveling with three other people at the conference, I set up an sms network and we were all able to keep in touch, letting each other know where we were, which sessions were going well, where the best coffee was, etc.
Simple. Cheap (free, actually). Effective. Everything you want in an app. I suggest you try it out at the next conference you attend. Couldn’t be easier.
And conferences, you should look to integrate these guys into your mobile apps.
