Although the influence & persistence of bloggers is now recognised on both sides of the Atlantic (next years US election may well be decided by the bloggers' input rather than Wall Street Journal or NYT op-eds), I'm pretty dismissive of a bloggers' union (http://www.techcrunch.com/2007/08/05/is-blogging-ready-for-a-unionized-workforce/ ).
No picket line? No brazier? Where's the sad-looking kid clutching unsold copies of "Socialist Worker"? Forget it, brothers & sisters!
