My Kindle has become my defacto reading device for all things digital.
Tonight I discovered the free http://kindlefeeder.com which allows you to email RSS feeds to your kindle. It’s pretty cool.
Just create an account. Your Kindle Feeder username becomes your email (ie: firstname.lastname@example.org) then allow that email to send stuff to your Kindle. Drop dead easy.
I’ve also been adding Instapaper clippings of websites I want to read to a downloadable .mobi file which I email. Handy stuff.
