Connecting blogroll to feed reader?

Anybody know a simple way to auto-add to my blogroll when I add a feed in my reader? Right now I’m using Stringer for consuming RSS.

I’ve found a bunch of plugins that do related things but none of them address this particular use case.


 

This isn’t the only use case for connecting my feed reader to my blog writer. I’d also like to be able to reblog a post right from the reader, with automatic pingback or webmention.
