Unicom are holding a conference in London on March 5th and 6th. It is called 'Web 2.0 and Beyond: Applying Social and Collaborative Tools to Business Problems.' They have a great line up of speakers. 

Focus Business Communications are again recording all the presenters for later podcasting. They have also interviewed a number of the speakers before the event and asked them what they would be presenting.

(Disclosure: I am speaking at the conference. I will be presenting a case study of a B2C blog/social networking communication campaign for UK High Street retailer. I have a financial interest in FBC)
