I was taught to use two spaces after a period (let's take "a period at the end of a sentence" as implied for this discussion) when I learned to type on an electric typewriter, but nobody seemed to care very much or enforce the rule. I used one space because two seemed unnecessary.
I also independently invented the European style of eating meat-- fork in left hand, knife in right, and use the fork to transfer the meat to my mouth. My father didn't like it, but he wasn't a very forceful person, so that's how I keep eating. I find it impossible to empathize with people caring strongly about such things, and I wonder if I'm a little bit on the autism spectrum.
And I was feeling the same way about the spaces after a period issue, especially after reading that very bad-tempered first link. However, I've been reading a facebook discussion where at least a couple of people said having two spaces after a period really does help them read, so I'm posting a poll. It's at livejournal because they don't propagate from dreamwidth and I don't want to create the poll twice.
