Paragraphs vs section headers 

Sorry, didn't mean to imply it didn't have "merit", any good faith edit on Wikipedia has merit. What I'm saying is, section breaks and paragraph breaks are similar, the question is when to use one vs the other. Paragraph breaks provide logical breaks in the content. In this case there is a new section header at the top of almost every paragraph, which is redundant, that's what paragraphs are made for. By adding those section headers, I believe, it chops up the article which discourages reading it as a single block of text from top to bottom, and encourages skimming and skipping, like reading an outline that hasn't been filled in, or a "list of" sort of thing, rather than a chronological and somewhat inter-related history of the origin of the high five. If we thought those origin theories were going to be greatly expanded.. say 4 or 5 or more paragraphs each.. I could see section headers making more sense, but until then, I believe it reads better as a single block of text. Green Cardamom (talk) 
I see what you're saying, but I disagree. I think it looks better the way it is now, especially with the long block quote in the first section. I mean, the other option to me is bullets, but I think we both would agree that's not that aesthetically pleasing. Without some kind of division, it makes it harder to see that the three options are mutually exclusive, or arose independently at best. Without the divisions, in my opinion, it sounds like one origin narrative that all together led to the high five, rather than three separate possibilities.
