From the about page:
In days gone by, people used to gather in public spaces to discuss the issues of the day, meeting like-minded people and generating ideas for action.
Nowadays, people rarely find time to gather and debate issues in person, but more and more find that the Internet can provide a way to meet other people, discuss issues and gain a sense of community online.
Bristol City Council provides a space, here at www.askbristol.com, where you can find information, access resources and of course, be part of the debate, whatever is on your mind.
