One of the challenges anyone faces in trying to engage with networked communities is finding what exists, who the participants are and who is the most influential people? 

Tools and techniques that can help in that task are most welcome. We recently interviewed Matthew Brazil, CEO and Founder of 6Consulting, a London based agency specialising in Social Media Monitoring and an authorised sales agent for Radian6 in the UK.

Radian6 has been gaining a reputation in North America and now the UK as one of those 'must consider' companies when it comes to tools to measure and track social media networks and their participants.
