You bring up good points especially with getting speakers and getting angels. I do plan to leverage the groups by having them contribute in setting up speakers and finding qualified angels. I'm more concerned about scaling this (that's the engineer in me thinking). At least five groups is somewhat manageable especially when it comes time to finding space to meet once per week.
