I used to be newsletter editor for our local caving club, and two-spacers abounded with submitted material. I do it myself, but I also use the excuse that most of the stuff I type is in fixed-pitch fonts, where I actually want there to be two spaces. Plus I learned to type on a typewriter and old habits really do die hard. But when I made the newsletter, I search-and-replaced them all to a single space. And I'm pleased HTML renders it properly no matter what. That way I can keep my two spaces when editing HTML in vim, but still see the correct rendering.
