I believe this was in a previous version of FeedReader: the ability to blog something I am viewing directly from FeedReader. Right now (correct me if I'm wrong!) I have to open a news item, go to its original website, and then blog from there.
To take it a step further, you might take a page out of Flickr's notebook and allow us to set up blog posting (including passwords) once in FeedReader and then all we need do is select which blog we are posting something to. If you need more description on how that works from the user's end, let me know.
Thank you!
New features + blogging = ecto
You asked us to suggest features that are something new and not only related to RSS reading. So here goes. A nice feature would be to add client side blogging abilities, something like ecto does.
