There is indeed very little that Calibre cannot do! I had been obsessant on Kindle since it came out, and finally with my final year KVPY stipend coming all late and huge - I splurged on a Kindle . .well and a Seagate GoFlex 1TB .. and an icecream at Baskin and Robbins!
Managing your kindle library with Calibre is a breeze.
But I didnt pay much heed to that big icon up there - Fetch News!
Turns out, it might have been the most important part of calibre for me. The interface is obvious, and they provide a little python API to write "recipes", which i intend to use when i feel like it to parse the xkcd json feeds. FYI somehow the standard python json module doesn't work with xkcd's json files .
The most interesting content for kindle are the tech blogs, most of which are already available from the default recipe list.
If they are not in the list, you would expect that you have to write a recipe! But wait, there is more.
There are two "Google Reader" recipes in that list that mean you dont have to write parsers anymore! If there are feeds, Reader reads them!
.. and oh! I resolve to blog a bit more!
