I think you are being a bit harsh. The meetup was never intended to be an event purely for the early stage startup entrepreneur. The primary goal was to allow the users of Hacker News to meet in the real world, talk about their interests and share experiences.

I've met many fascinating people there, who between them have been through all stages of the startup life cycle and made many new friends.

I am sorry that you got stuck talking to a bore. In my experience people like that have been very much the exception rather than the rule.

Anyway, I value all feedback and want the meetup to be as useful and interesting as possible so if you have suggestions or ideas on how to improve it I would love to hear from you.
