Sorry for the delayed response, Lynn. I've been "out of pocket" with limited internet access.
I really like the idea of back-channel conversations and intentionally bringing those to the forefront because such good thinking happens in the subtext. My dilemma at this point in time is that most of those I am working with are limited social media users. They use email, probably text a bit, and might be on Facebook, but those are the outer limits. My desire is to start where they are and build a bridge for using the familiar tools in new ways that increases participation (both "out-loud" and observational) of those in the small face-to-face groups who do not have a computer in front of them.
Does anyone know of any text aggregators that would bring all text messages sent to a certain number into one location...like a twitterfeed...that could be accessed by all of those on computers so they could be projected for all the individuals in the small groups to see? Or other ideas for how to create, capture, and share back channel conversations using simple cell phones (not smart phones)?
Wow, good question. I personally haven't heard of any. Sorry!
It's really interesting how when you begin to explore something new that related resources seem to find their way to your door. Just this morning I received a link to this blog about group texting applications: http://www.frogloop.com/care2blog/2011/4/25/group-texting-useful-or-hype.html and LaDonna Coy shared wifitti with me. I haven't had a chance to explore these tools...if folks have recommendations or are willing to share their experiences with any of the tools, I'm eager to learn from you!
