Sentence Spacing — 1 Space or 2?
An anonymous reader noted an epic battle is waging, the likes of which has not been seen since we all agreed that tab indenting for code was properly two spaces. He writes "Do you hit the space bar two times between sentences, or only one? I admit, I'm from the typewriter age that hits it twice, but the article has pretty much convinced me to change. My final concern: how will my word processor know the difference between an abbr. and the end of a sentence (so it can stretch the sentence for me)? I don't use a capital letter for certain technical words (even when they start a sentence), making it both harder to programmatically detect a new sentence and more important to do so. What does the Slashdot community think?"
The linux Kernel is (was?) 8 spaces. The idea between 8 space tabs is that if your code is indented so far as to be a pain to read, then you should probably look into why it's so nested.
So, in our efficient, modern world, I think there is no room for two spaces after a period. In the opinion of this particular copyeditor, this is a good thing.
Efficiency has nothing to do with it. In fact, efficiency is a complete red-herring, since presumably in our efficient, modern world we could simply write software to be intelligent enough to automatically add a space between sentences when it detects a period-space-word starting with a capital letter.
The reason you add two spaces is because the additional space aids your eyes in determining individual sentences. If you only use a single space to delineate words and sentences, all paragraphs merge into a jumble. Two spaces gives the eyes an additional visual cue, and thus is far easier to parse.
and it's from quite a credible source
An appeal to authority is less argumentatively valid than an appeal to reason. The Chicago Manual of Style gives no reason except some hand-waiving about our "efficient, modern world," which is a huge, steaming pile of bunkum.
