This is one 'block' of text.
This is another. Padding this out a bit more so it wraps enough to demonstrate what I'm referring to. There's clearly (well, clearly to me) an extra buffer space between the <p>s? It's small, but it's there; as bwatford said, it looks like it might just be 0.2em or so. Hitting ENTER should function just like a normal line break (ie, no extra padding or margin at all, I can't even fathom why it was included in the first place), not this weird, failed attempt to create a new block of text. Unlike the line spacing between this "paragraph."
I know most people don't/can't see it, but it's one of those minor things that I picked up on immediately.
As for the WYSIWYG error, I'm typing this line in it right now to show just how big a gap there is between paragraphs and lines. I'll edit this to show the difference in the actual post afterwards.
