I like the aesthetics of two spaces, as well. Especially when using a proportional font since a proportional space is narrower than an average character width.

I like the aesthetics of two spaces, as well. Especially when using a proportional font since a proportional space is narrower than an average character width. A "." and a skinny space doesn't provide much of a visual separation. I've gotten over not liking seeing a single space from others, and others can get over seeing my double-spaces :)
