I’ve been saying all day how sites I enjoy the most and most want to support are the sites I usually read on their website. But Justin Blanton has been piping them through Readability for years. Why? For consistency and efficiency in his reading:

For the last couple of years I’ve routed everything through Readability, no matter how visually pleasing I find the site, or how easy it is to read its text. (I stuck with Readability even after Instapaper offered a similar bookmarklet.) I really don’t care how good your site looks, etc. — I want a consistent reading experience no matter what I’m reading (mainly because, over time, it makes my reading more efficient).
