What else to add to Google Reader?

Exiting GR from beta disappointed me. Of course, searching the subscription base, statistics and the option of hiding the column with folders is without a doubt a pleasant thing. But the user, as before, is in the "box" of his own interests without any system function of communicating with his own kind and expanding the RSS outlook. The Shared Items function in this sense is a half measure. All that can be done is to send a long, terrible link to a friend, with the words “Read what I’ve picked up”
So, I don’t know if Google representatives are reading Habra, but I’d like something else ... (am I not alone?)

1. The system of matching threads to identify users who read similar topics or matching threads. Analogue of neighbors on LastFM.
2. The ability to directly subscribe to their Shared Items. And not only for everything, but also with the help of filters. Imagine how convenient it is for lack of time to read not everything, but the information already selected by a reputable user.
3. Whiteboard for each user. There must be the opportunity to publicly thank the one who rakes for you the heaps of rss.
