I've been using IFTTT to do this - Pocket isn't good at handling the volume of RSS items that Google Reader could, but neither am I. And offline reading is killer.
It would be nice if it worked with the open source alternative also, Wallabag.
Thanks for the input. I created an issue for it https://github.com/mocco/feedhuddler/issues/52. I haven't looked into wallabag, so I don't now if we are able to do it. The issue will be updated with status as I look into it.
I am using IFTTT to add rss feeds to Pocket, but this seems to be less complicated to use!
For Instapaper users: I'm doing the same thing with the help of IFTTT.
