That was a very readable comment. I'm reminded of the times I've posted here about "If it's 3 paragraphs or longer, my coworkers won't read it" only to get responses like "Must be poor writing on your part!"
It looks totally fine on a monitor, but because of the narrow width on cell phone displays, a paragraph can extend beyond the display's height, and it psychologically has an impact on people.
I really didn't think the "linkedin-style spacing" was necessary. The OP was not exactly short, but had a good enough sense of spacing and used paragraph breaks appropriately.
