Columns like those are a bit awkward when combined with scrolling long blocks of text. When you reach the bottom of one column, do you need to scroll back up to get to the top of the next? Or do you have the column fit the height of the screen and have some sort of horizontal scrolling for as many columns as it takes.
Why not limit the height of the columns so they fit on the screen, and wrap around to new columns lower down? So when you reach the end of the rightmost column, you scroll down the page and continue reading at the leftmost column.
I've experimented with this style on Wikipedia, with separate columns under each headline. It usually works well.
