Finding a Feed Reader for Google Reader Shared Items

[NeoDevin]

I'm currently using google reader as my feed reader, but due to a lack of some features (the biggest ones are nesting folders, and the ability to mark previously read items unread again) want a different reader.

The only thing keeping me from switching so far, is the "shared items" in google reader, and the ability to comment on them. It makes it so easy to let your friends know about things, and to discuss them in a context you might not want posted on the blog for everyone to read.

I don't suppose anyone knows of a feed reader which can interact with google reader's shared items/comments, and also has these other features? (even better if it's open source)

Thanks in advance.

I've always used Feedburner, but that is also a Google product.

I use theoldreader web site, the greader android app also can use it as a source.
