I recently wrote a small webapp to allow me reading my Pocket and Twitter timeline articles on my Kindle, during the daily commute. Got some good feedback from friends, so posting here, as I guess it might interest other readers. It'll check for your unread articles, download their content and send them to your Kindle as daily edition/megazine style booklet. You can also archive & favorite stuff directly on the Kindle (provided you're connected to 3G/Wifi).

It's all free for now (I intend to charge something eventually to help pay the server bills, if people start using it regularly :-P) - all feedback is super welcome!
