All I gotta say, Steve Shaw, is that you posted the 300th message in this thread and didn't lay claim to it.

Why?

I've seen it a lot and always regarded it as an odd habit. 300 is no more special than 273, for example. Actually, to a physical scientist, 273 with a minus sign is far more significant (and I picked 273 there by accident!)

OK, pedants, 273.1.
