In theory the Net should be a good way for like-minded people to connect and develop ideas, or solve problems, to benefit their local community. But who is doing that - or facilitating it - effectively? Jonathan Briggs, who runs the Reengage blog commented on my speed networking post, saying "I'm really up for some further discussions about how we use technology to link people to other people to solve small problems. Dating sites for problem solving? ;-)"
Jonathan's query promoted me to look again at the 'Who's who in community technology' pages I started a few years ago.
