Hmm. This is SERIOUSLY interesting. I will get me one of those suckers.
By the way, in the Aperture thread, somebody complained about the number of people spelling it Aperature. I suspect that's a back-formation from apparatus.
Anyway, I'd take that (fairly uncommon) misspelling in exchange for all the people who write "loose" ('not tight') when they mean 'lose' (to misplace, to drop out) as well as people on a photography forum who write 'lense' when they mean 'lens.'
It's weird; almost everybody here is smart. But a large number of us can't spell.
How many people here know the English word with the most consecutive double letters, without googling it?
