I don’t mean are we alone, I mean how many we should use. Read all about it here.
It always fascinates me when people get hot under the collar about something trivial. I like consistency, & I understand the reason behind the fashion change on the number of spaces after a full stop. But as long as it looks tidy in something important, why does it matter? Surely what comes before the full stop is the interesting bit? If detail really matters this much to “everyone” how come so many people can’t grasp the basic idea of the apostrophe?
For what it’s worth, I favour the single space, as it takes half the effort. I used to go for two, to demonstrate I knew what was correct. Then I found my colleagues didn’t know. Most didn’t even notice.
And how they can call it grammar beats me entirely.
