Two spaces after sentences drive me insane. It's wrong. It's been wrong for half a century. So, if any of you have teachers who, like my old teachers all the way through college, tell you to use two spaces, point them to this link:

It amazes me how many people still cling to typography rules that were originally created for use on turn-of-the-century typewriters. Occasionally, I still see a publication or blog use two spaces between sentences and it drives me up the wall.

So...  Why do you think this is?  Personally doesn't matter to me

Yikes. That's just bizarro-world shit.

Wow, I just had to google that and some people in a convo on wikipedia say they were taught to put two spaces as late as 1990. Personally I never encountered that (I've seen people consistently not leaving a space quite a few times, but never consistently two).

Was that practiced only in typewriter typing, or also in books? I should check at my parents' place tomorrow, the oldest printed book at my place is from 1966 and definitely only has one space after a full stop.

Never even heard of it, to be honest.

man some people waste too much time complaining , and if they don't find something to complain about ,they waste too much time seeking something to complain about.

i love complaining about complainers.

Wasn't it necessary to get automatic capitalisation at the start of the next sentence in earlier versions of MS Word/Works?

I.  Will.  Not.  Stop.

I am a slave to Word. It wants me to do one space, so I only do one space >___>

Why would you need two spaces?
