I saw an opportunity to educate the public, bring like minded people together, and to provide a valuable social resource do discuss the RWD tools and methods in particular but the larger software development practice in general.
Present events related to topic on regular basis.
Pass knowledge on to the community.
Help people find jobs, fill roles.
Formally create group and open it for all to become members.
Study how group grew over time and hosted first event.
Chilled out from there really.
There really wasn't much design for the group, it was about getting other designers together to have a positive social impact.
I also got a chance to improve my leadership and speaking skills...
