So, what’s your opinion? A, B, or C?
[A] Two spaces after a period is the proper way to set type.
[B] With the white space above the point, one space after a period is all that’s needed.
[C] The physical space after a period should be thinner to compensate for the optical whiteness above the period.

One space is a perfect sufficiency.
Two would be an unnecessary extravagance.
Oh, and it looks f‑ugly.

This whole fake argument about the typewriter vs. proportional fonts is asinine. The purpose of using two spaces after a period was never related to the typewriter or proportional fonts. Its purpose is a visual cue to improves legibility.

Better late than never: One space after a period unless it is a fixed-width font (e.g., Courier, or a typewriter). Two spaces after a colon. I would agree with other opinions if they were not wrong.
