I really like Readability. I used it as one of my contributions to ABA TECHSHOW's 60 Sites in 60 Minutes 2009. It actually isn't a website you will visit often because, if you take my advice, you will visit it once and install the Readability applet link on your browser links bar. Readability "is a simple tool that makes reading on the Web more enjoyable by removing the clutter around what you’re reading." If you have reached a certain level of maturity, you can also set it to make the font bigger so that it is easier to read.

Whether this helps a person with vision problems read online better or whether it is just better when you are reading from your laptop during the commercials as you watch TV, (like Tom Mighell, who referred me to the site) Readability is a nice tool to have available when you need it.
