Now here's something that almost defines the phrase 'armchair activist' - although I suppose 'desktop activist' is closer.
Apparently you can sign up to join the Gleneagles G8 demo online and appear there virtually. Just think of all that shoe-leather we've wasted over the years....
However, I have to say when I tried the site it seemed to be frozen. Perhaps it's crashed. I'll try again later.
