Memo to Neal Lawson
Neal - keep suggesting collaboration with the Lib Dems like you have here: http://commentisfree.guardian.co.uk/neal_lawson/2006/08/
You will find it makes both you personally and Compass as an organisation immensely popular with Labour activists and councillors who spend their time fighting the LDs at a local level. And particularly with Gordon Brown's inner circle, several of whom helped set up Lib Dem Watch.
As a benign observer of Compass I couldn't recommend a better strategy for you.
