Playing around with calibre I must say I like this program more and more. Although really sluggish on startup, it seems to be a nice news reader which has a large and interesting repertoire of web sites providing news, which one can download into e-book format for later perusal. It also has a cool animation for flipping through book covers. Thanks extendedping for drawing my attention to it! I also can report that upgrading calibre to 0.7.18 as provided by Debian sid is no problem. Below is a screenshot of that version.
