re: Two Spaces or One Space after a Sentence?

2 was for the teletype/typewriter days. Now a'days, one is the only way to go, if you're under 90.

2, and I will go down with the ship.

Put two if you want. I still do but almost all screen displays and printers use a proportionally spaced font which compresses it to one space.

Two spaces looks sloppy.

One is universally acceptable.

2, just like the number of dads in your home growing up.

It's one now. The 2 spaces was a vestige of typewriters where 2 spaces was needed to better break the sentence. On a computer, the program already makes the space large enough that it's not an issue. I learned 2 spaces because I learned to type on a typewriter and sometimes still do it when I'm not thinking.
