Yes, a double space after a point/period/fullstop was the tradition taught by the (UK) RSA in all typing qualifications they provided and oversaw. Like Jazzo, having been used to this visual clue as to separation of sentences, I hated the auto feature of WP packages that tried to insist on single spacing, and still reject that layout. It is particularly annoying with justified or force-justified text, since the rather arbitrary word spacing can leave the eye skipping to the end of a sentence without visual warning of the end point approaching - I sometimes find this causes me to re-read sentences, because I had started to wrongly model the emphasis or stress patterns as a result, and thus got a distorted meaning. So here, after 'meaning', there is still the double space I was originally taught (whatever the HTML code does with it): not because I automatically cling to that, but because I believe it is functionally useful.
