I attended and eventually managed a local meetup of entrepreneurs. It was a highly, highly valuable and enriching experience. Met people from all walks of life, in all kinds of businesses, with common goals among all of us. We would sometimes have meetups where we simply chit-chatted and shot the breeze while others may be topic-centric (discussions about tax loopholes, legal entity selection, social media marketing, etc.). Meetups, I believe, are invaluable.
