I gave Twitter a bit of a kicking in my last blog. Since then I’ve been wondering if that was fair. Time was when I did a forty mile commute into London, not daily but often three times a week. I would have dearly loved a way of whiling away the time that did not directly involve work. All I had was that house-brick cellphone – it was so heavy I’d swear it had valves. So, a reprieve for Twitter, maybe. It’s still raining, but the fire engine has gone from outside Asda.
