Sentences: Double or Single Space?

out of curiousity, which of these paragraphs is easier to tell the sentences apart?  really, the answer is obviously the second paragraph.  do you know what the difference between these two paragraphs is?  the first is obviously double spaced.

And this one is single spaced. See, it's capital letters that distinguish sentences, not spacing. Isn't this lovely to read? Much better than the first. The first does not capitalise the first letter and is thus rubbish.

Voted Single.

I would argue -- did argue above -- that the first is only harder for you to read because of what you are familiar with.  I think "double space with no initial capitalization" and "single space with capitalization" have equal informative value as to the beginnings of sentences.  (Again, I am NOT advocating anything about removing that convention.)  Although I disagree with RolStoppable's argument that it is so redundant that it is practically worthless, I think he has a much better point than you do.
