I like how clean Scripting News looks in the markdown version. No tabs along the top, no column of links (blogroll) along the right, just an emphasis on the text. Clean. Easier to read. Loads fast and the reader can select different type faces, so I can select one that makes rendering on a eInk tablet look nice.
Another thing I find interesting is that it looks like the “browser” treats markdown heads as in-page hyperlinks. Mouse over a heading and you see a icon appear to the left, which when you click scrolls the page up to put the head at the top. I think this might be useful for large pages like my Daynotes, I imagine being able to create a table of contents at the top to jump to the months of the year.
