Spaces between sentences

Today I learned that I am archaic, an anachronism, a dinosaur, a throw back (and redundant too).

Apparently, my use of two spaces between sentences is now wrong, wrong, wrong.  And bad mommy, I've taught my children to do the same.

A site that explains this quite clearly and firmly is Typography for Lawyers:  www.typographyforlawyers.com/?p=12

I, however, remain defiant and will continue to use two spaces until the spaces police come for me.  Buh wa ha ha!
