Auto-reformat Web articles for easier reading: Readability (free)
Very cool.
Get it here. It’s free.
UPDATE: Some serious issues with Readability: rip-off artists, I see. I have been using Instapaper.com, which puts a button in my browser “Send to Kindle” and will also save articles (i.e., titles and links) on my page at Instapaper.com, so I can easily return to the article. I found Readability only this morning, and based on the information at the link, I’ll return to Instapaper for when I want the article, and use Readability only for on-screen formatting.
Thanks to John Anthony Grigutis for pointing this out. (See comment.)

Readability had a bit of controversy a few months ago because of the way it redirected shared links back to its own site instead of the original site. They have since changed that, but there is still some bad blood about the way it pays for (or doesn’t) the content that it hosts. Daring Fireball outlines the issue.
btw, I highly recommend adding Daring Fireball to your daily “sites to read” list.

Many thanks for pointing that out. I’ve updated the original post. Readability’s actions exemplify the unethical behavior of businesses, who must be watched constantly and never trusted. Businesses are sociopaths, which is why it’s too bad we’ve turned the country over to them.
