My instinct, is to include two spaces after a period. I think this is largely due to a business studies class - where I was told that 'two is standard'. It feels weird to only include one space. My tendency to add two spaces, provides me with a tactile confirmation that I've ended the sentence - which seems to add positively to the rhythm of writing. I'm not sure I could break the habit of including two spaces even if I wanted to; I touch type and I think the process of typing is too deeply embedded in my brain's neural networks to change it now. No matter how many spaces are included - when presenting text, one space after a period, can always be rendered as standard; so I'm not totally sure what the problem is. Happily, two spaces are rendered as one in HTML markup (unless a   entity is used.
