A way of making something stick comes down to regularity of message or the idea and the amount of enjoyment you get from it. Ok, I'm not a psychologist but we gravitate towards the things we prefer. Now there exists a number of meetups already on innovation, business startups and entrepreneurialism - but cities like Melbourne, Sydney and Brisbane hold regular evening learning sessions in pubs, clubs and cafes where not only do you get grub and drinks and socialise, but each week some speaker or teacher provides a prezo on topics from sustainability, cosmos, medicine etc. I think a fun way of community learning and engagement can also help bring ideas together like a broader 'connection'. I think the current meetups are limited by their focus on 'business' alone.
