I think it’s fair to say that Wikipedia is one of the greatest things which the internet has given us. For it to continue to be free, there’s a permanent fund-raising drive taking place, and I implore you to support it. If I gave one penny (just one penny!) for every time my family used Wikipedia, I’d spend considerably more each year than the ten pounds I’ve just donated, and which is apparently the average donation. So if Wikipedia has ever saved you time, effort or professional embarrassment, do go and support it now. It’s a one-click Paypal or credit card transaction.
