I just conducted my first meetup group meet this yesterday.
If you are not aware of meetup.com. It is like facebook for meetings. You can attend all manner of meetings I have been to quite a few it is a great way to meet like minded people. The list of different types of meetups in melbourne is large. I have been attending meetings on things around programming, SEO and entrepreneurship
I have also started a new website for me to post about critical thinking and to support the meetup. Its a very pretty site and has an awesome video.
