I really like these initiatives. It creates a support network to help early startups get to market.

However there seems to be lots of these popping up and you start to question the longevity of these groups. I am sure these are started with good intentions however what are the motivations of the organizers?

Is it simply the buzz of being involved and sharing ideas/stories/support?

I am not trying to criticize the groups, but interested in the risks of getting involved in these events/communities?

Do you need to be cautious of anything? How do you select the right group or groups to join?
