A brilliant button for your browser toolbar that actually works:
READABILITY: The single best tech idea of 2009, though, the real life-changer, has got to be Readability. It’s a free button for your Web browser’s toolbar [get it at lab.arc90.com/experiments/readability]. When you click it, Readability eliminates everything from the Web page you’re reading except the text and photos. No ads, blinking, links, banners, promos or anything else. Times Square just goes away. You wind up with a simple, magazine-like layout, presented in a beautiful font and size (your choice) against a white or off-white background with none of this red-text-against-black business. You occasionally run into a Web page that Readability doesn’t handle right — no big deal, just refresh the page to see the original. But most of the time, Readability makes the world online a calmer, cleaner, more beautiful place.
Why didn’t I think of that?
If you like Readability, you really need to look into using Instapaper. You use the bookmarklet like Readability, but then once you get a bunch of files, you can export them to a file which will import to your Kindle.
