Since I got my Kindle (Kindle 3) I’ve been using Readability to send articles and post from the sites I frequent over to my kindle. Readability is a great product similar to Instapaper and Read it Later, but it adds a few features specific for Kindle users.
Readability converts web page into a clean and distraction free reading content. At the moment it has extensions for Chrome and Firefox (Bookmarklet can be used for other browsers) and a great mobile web app for iOS and Android browsers. iOS and Android apps are in the works.
On January 10th Readability announced that it was now a free service (before that you would only get your last 30 entries for free) which is great for those who wish to use it as a filing cabinet for articles.
The Readability extension gives you three options: 1) Read Now, 2) Read Later, or 3) Send to Kindle. Option 1 and 2 will send to output to your reading list on Readability.com with option 1 giving you the Readability version of the article immediately. Option 3 work pretty much like Read Later but will send the output the your kindle email address. I prefer to use option 2 and have set up Readability to send me a digest of all my articles at 4 a.m. which is set up like a periodical subscription which is replaced each day. The digest includes a neat table of contents on you Kindle so you can browse through your saved items.
Here is what an article would look like after being sent to Readability.com.
