I now live in fear of posting more than a sentence here

Oh, don't! Seriously. For all the editors/writers here, I've never seen anyone lay a grammar smackdown on anyone else. The serial comma debate is just good-natured heckling between nerds.

And even the editors/writers here don't have flawless grammar when posting. God knows *I* don't.

Kevin, which Prime Minister and why didn't it stick?

Typos are why we have the edit function. If they drive you nuts, you can fix them. If not, that's fine too.

I used to automatically do the two hits to the spacebar, but my current keyboards feel so different from typewriters that the muscle memory has been overridden.

Teach me!

As soon as I remember, I'll tell you!

We have a massive, multi-page macro at work that covers all the really common things that authors do that violate our house style -- lots of minutiae (like no periods in academic degrees -- MD, PhD, etc.), but that's our thing. We just run it first before we ever start editing.

And even the editors/writers here don't have flawless grammar when posting. God knows *I* don't.

Oh, god, me either. And I use ellipses and em dashes far too much here and in casual use.

I remember being taught the two spaces after a period, when I took a typing class with a real typewriter, but as soon as I switched to computers with word processors I quit doing that. I'm not sure why, somebody must have told me because I rarely think to change my habits that way. What did surprise me recently was taking a typing test on a computer and the program specified I was to put in two spaces after a period! It made me wonder, since this was a test for a county job, if the county still had scads of typewriters in use in their offices.

Gordon Brown, or Tony Blair?

Why was two spaces needed for typewriting, but not now?
