When I learned to type, I learned the two space convention. Some years ago, while working together on a paper draft a friend of mine hooted and laughed at my antediluvian practice. When he was done, I explained that the paper was destined for LaTeX, and that any amount of space would be collapsed into Knuth Standard Spacing. The joke was on my friend in the end, as I convinced him to learn LaTeX, which is the most useful cruelty one can inflict on someone else.
