I've just found a very easy way to read articles from the internet on your Kindle.

1. Create an account at Instapaper
2. Enter your "@kindle.com" email address to your Instapaper account
3. Enter you "@instapaper.com" email address to your approved emails at your kindle account
4. Download a special java bookmark from Instapaper and add it to you browser.
5. When you find an article you want to be sent to your kindle for later reading, just hit that special bookmark and it will be added to your Instapaper reading list
6. You can send your reading list to your kindle at any time by going to your Instapaper account or configure it so it sent automatically every day or every week (at pre-specified time).

I used to achieve the same thing by copying articles, pasting into work document and emailing word documents to my Kindle. Now all I have to do is press one bookmark button and it is all done for me. In the evening I bookmark articles, the are sent to my Kindle during the night, in the morning I switch on my Kindle and it downloads my offline reading for the day.
