A few slides to layout the principle of different feedback loops between your online community, your site, contributors, readers and other blogs and communities. Any feedback?

…And thanks to tweet-feedback from Jenny Ambrozek (@sagenet) for the wider context around the power of feedback loops – see the Fast Company article on how Ning is using this concept (what they term a ‘viral expansion loop’) to great effect. [I’m currently at the British Computer Society at Covent Garden, so looks like I’ll be reading the print-out over lunch].

PS: It’s also a key way in which the world’s biggest social network site Facebook, by implementing the ‘status update’ feature, managed to rapidly grow its membership, as I outlined in a recent post. In other words this is a very powerful tool if done well, and with something people want. Anyone want my viral loop consultancy better get in touch quick as I’m off to see a London-based social media agency about this on Thursday!

In the meantime I’ve ordered Adam Penenberg’s book ‘Viral Loop’ (see the Amazon widget on my homepage to order a copy) after a ‘winning streak’ of blog posts on the power of networks & feedback loops led me to his virtual door. If you fancy creating some feedback loops, or plain user flows for that matter, I’ve tracked down what appears to be a useful site: Product Planner. It allows you to create your own viral loops and check out some that have already been created.

And of course I did a very quick search today on Twitter on the key phrase ‘viral loops’ which unearthed this gem of a slideshow, from Josh Jeffreys (Interactive Creative Director at BusyEvent) which provides (in his words) an overview of how to build applications that have built-in mechanisms for driving users to recruit additional users through normal use of the application. Look out for the new acronym ‘UDU’ (users drive users):Viral Loops: Making Self-Marketing Apps
