Multiple columns still make sense for certain types of content. There's a reason news papers still use them centuries later.

Single column only works on a single page/article/concept being shared. Beyond that, it gets a bit silly to get from point a to b, but there are times when multiple columns still work.

Maybe when I'm done with reading, I like to check out related links on the side. I'd rather not scroll all the way to the bottom to do that. Or if I run an ad, I want to make sure the placement (though still outside the main body of the article to not be distracting) is still at prime real-estate.

Do X for a better Y is always tricky business. It's sometimes not as simple as one column.
