I, personally, have taken adavantage of this on numerous occasions. I couldn't stand when it lumped it all together into one large paragraph, epsecially when you might comment on several aspects of a particular subject in one review.

While less taxing on the eyes, I find people often end up leaving posts with excessive spacing and lengthy posts taking up even more space than they would have previously occupied.

It's nice. Helps with the flow for writing & reading. I gotta work out a few things with the way I write (i.e. making sure there's not any extra enter's after the end of the my text which results in big, blank spaces on the bottom). Overall, I like it.

I think it's a keeper. It sure is easier on the eyes.
