I cannot imagine the Internet without Readable ( http://readable.tastefulwords.com/ ). It's like Readability but not slow. Oh, and customizable!

Thank you! I've been looking for something else ever since Readbility switched to their newer, heavier, slower version.

You can still find the old version of Readability if you google around. For example, http://www.tobez.org/download/readability.html

It's a fashion website. Aesthetics (and brand) are usually prioritized over functionality.
