It's funny that such a flippant exchange is actually hugely significant for the English language. As most Roman text across the World is now consumed via HTML this brief discussion put the final nail in the coffin for the double-space-after-sentence jig.

The fact that the exchange is recorded is magnificent to me. We don't have a written dialogue of the guys who decided to start putting spaces in English words in the first place...
