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 neutral with a mild preference 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 let's have a poll.
Do you notice whether there are one or two spaces after a period?
Only if I'm editing
Do you have a preference, and how strong is it?
Strong preference for two spaces
Mild preference for two spaces
I don't care
I don't care! I don't care! I don't care!
Mild preference for one space
Strong preference for one space
I just want to see the results
I wish to complain about this poll
