Agree totally, that content is the most significant item which draws people to use such forums. And as you say EDF is the most successful because of both it's content and level of usage. One drives the other and vice versa.

I am hoping SE23.com can increase its reach and usage, through more local content being posted on it. Looking at local twitter sites, they have content which comes from those who own the accounts/users, and which details things that have happened, are planned to happen and general events not recorded elsewhere. Maybe some of those interesting items posted across the perhaps 5 or 6 local twitter sites can be collated into one place here?
