Because you can't spell fundraiser without fun! har dee har har.
But, yes, a wee ask for some donations to help keep this humble blog going. This isn't charity, if it was (as in I was in desperate need) I would say so. Don't give me your help victims of natural catastrophes money, give me your expensive bottle of scotch money or your Washington Post subscription money. And of course no need to give at all. Always grateful for donations received, but certainly have no expectations about it.
This blog is much more time consuming than many people think. It's still a privilege to have something like this, and I usually don't forget that, but sometimes it can be a long hard slog...
