How to describe HarringayOnline.com

I've shared a few Hangouts with a US E-democracy advocate - Steven Clift. He's a congenial guy, active in Network Neighbourhoods and will be over here in October. . Here's what he posted on another forum:

---------------------------

It looks like I'll have much of the day on Monday, October 20 to explore civic tech/open gov/open data in Manchester.

I'll be at SOCITM on the 21 - http://www.socitm.net/events/socitm-2014 - folks here should ping me if you want to say hello.

On Wednesday is my Consultation Institute conference keynote -
http://www.consultationinstitute.org/events/conference-2014/ - where I'll share major lessons from our "e-democracy" movement from the first twenty years(!). This will be a completely new speech.

On Thursday, I am working with Involve on an event focused on emerging "Facebook-native" councillors and "friending for office." We are looking for interested sponsors to cover some costs. Ping me if interested!

At some point I'll be visiting our neighbours online project in Norbiton in Kingston upon Thames: http://e-democracy.org/norbiton (p.s. looking for web-friendly open source Mailman replacement - note that we use http://groupserver.org )

On Friday, I'd love to meet folks from places like ODI, OKFN, the parliament's digital democracy commission and others. Suggestions?

And Sat-Sun I'll be at Mozilla Fest. Monday morning I fly home to Minneapolis.

Also, I am super passionate about "neighbourhoods online" be it on Facebook Groups, some other platform, e-democracy.org ... as long as groups covering large areas aren't private resident-only "gated communities" only really serving home owners. I do like resident-only
online spaces for streets and buildings. So, if you know projects doing great and inclusive work to connect neighbours online, please make an introduction.

I began to write a description in reply to his email but many others here are much more experienced than I on HoL.  I thought to try to pick out the 'highlights' but am not aware of all of them, and have had difficulty finding the 'key' threads for, say, the St Anns corruption, the Banksy thing etc. I'd like to set up a meeting locally if there's enough interest.

Can anyone please help describe this site to a stranger who has a lot of experience of similar sites elsewhere?
