Someone should do a Schoolhouse Rocks cartoon about how a joke becomes a meme.

Well - now - I'm - stuck - in - 4 - chan - slash - b!

And - I'll - sit - here - and - wait

While - a - few - key - college - kids - discuss - and - debate...

low signal-to-noise ratio if you ask me... I don't understand why this gets upvotes.

That's what the "flag" link is for. (You're new here, so I'm not being snarky - I realized you might not have noticed it.)

Maybe I'm being dumb here, but what's the 'one space after a period' rule about? I put two in out of habit and have never thought it a problem.

It doesn't seem to make sense as far as mucking up layouts go either. The extra space is dropped in HTML for a start and if it wasn't, any site that can't handle a couple of extra spaces isn't going to fare much better with any other text entered.

The two space rule was based on the monospacing used by typewriters.

With proportional text, one space typically creates better typography.

That's some good fucking advice!
