Own up ... how many times have you tried to visit Wikipedia today?
Unusually low traffic here today, and I've made only two abortive searches, when I forgot that there's a blackout.
I can't remember when I got the habit - whoops, have just googled vainly to find when Wikipedia began - but certainly 10 years ago I would have had to survive without knowing what tops and noils are. (Reference that passed over my head, relating to the wool industry, in Hockney biography. I know now. I'll have forgotten again by tomorrow. Maybe it will surface one day when I'm watching University Challenge.)
Attempt two was utterly trivial search for information about a famous actress who I may or may not have seen yesterday, but was confused because a) she was shorter than I expected and b) if it was her, she was wearing really awful trousers ... so maybe it wasn't her.
So I had to find out how tall she is. (I won't embarrass the famous actress - who appeared in Cranford - in case she really was in the West End in a pair of awful trousers. I mean, you should have seen what I was wearing ... )
I sometimes wish that Wikipedia would operate a Need to Know facility.
Of course, yesterday I really did need to know about red pandas in China. Honest.
