No. Brands don't belong on Twitter. SMS but broadcastable and searchable, in-pockets and topical, all good. Great for people. Lousy for "advertisers" unless they have something really interesting to say. "Check my features" just doesn't cut it in this environment. Positioning is not personality.
The current "green-everything" agenda seems quaint and useless when you consider the facts. It would almost be funny if it wasn't so sad. The hijacking of the agenda by corporates just obscures the real issues and for that reason M&S "Plan A", to name just one campaign, is part of the problem and not the solution it pretends to be. The real problem is that we're not nearly scared enough; crappy feel-good cop-outs get in the way of meaningful debate.
I'm reminded of deceptions like the "how to survive a nuclear war" public information films . Looking back they are a weird assortment of reassuring bunkum from people who should know better, talking down to people who have no real idea (and probably can't afford to care). It's just offensive; Do remember to shut your windows and listen to the radio while civilisation burns around you.
Evidently China's Co2 production from the manufacture of cement alone (they have 85% of global capacity in this), is greater than the total UK output. Sadly, cement production cannot be made greener, it's just one of those things.

And this is just priceless,
So let's compare this advice with the reality of a nuclear strike.
Here's a great mashup on Gmaps for you to play with. On a brighter note, at 14m of sea level increase my house is going to be on the beach - time to open that surf shop then. Chelsea's not looking too clever, but no great loss IMHO.
