Yes, I use that and also have Instapaper/Readability regularly mail me articles. It's helpful but these are still hacks.
1) It's horribly painful to organize the articles, especially when spanning multiple pages
2) I have to know about the article ahead of time to send to the kindle, rather than discover on the device itself
3) I can't "Mark as Read" on the device itself right after reading
4) For Instapaper/Readability, only the latest ~20 articles are shown. Also, the API Amazon provided used to frequently break.
