Probably the best meetup I attended so far, 2006 Holidays Event! - NYC Podcasting Meetup featuring a talk by Jason Van Orden at Ariel Publicity - had about 20 members attending.

Jason Van Orden, author of "Promoting Your Podcast", had a lot of good things to say ..and we were all listening. 

I spoke to several well known podcasters - meetups are great for that kind of meeting - will write up more about this meeting in a couple of days, when I have more time.

One take away - Social Media is about Trust; it's no longer about interruption - it's about engagement and leading people to want to look at your content.
