Growth Strategies for Online Communities

I'm not sure who was the target audience at the camp, but I was surprised at the basic nature of this presentation. This is the same advice from the 90's.

It seems to me there are other growth strategies, but they involve thinking beyond the walled garden model.

Thoughts? 

To be fair, this presentation was designed to be 3 minutes long, punchy and simple - to start conversations.  There was a followup presenter, but a) I did not get verbal permission from her to reprint her presentation, b) I actually changed sessions because - yes - this is following a very classic "come to *my* community" model.

More of my thoughts on the conference here - which is where you'll get a gist of what my "gestalt" of the conference was, and what I think are the more interesting and necessary models for the future (given the work I do, not necessarily any other "business models").
