A leaked video from google reveals there next evolution :

• Google will work on a standard for feed publishers to tell aggegrators about changes in the feed
• The Reader team is going to integrate more social features
• Google is interested in allowing users to comment on items they share
• Very soon, Reader will recommend feeds to the user, based on previous subscriptions and other Google activity.
• Reader might be more directly monetized in the future, but Google wants to watch out showing ads next to other people’s content. This is a problem with Google News too. They might do something like they did with the non-free Opera: show the content owners’ ads in the interface when they’re AdSense publishers.

At my first look at the Google reader i didnt like many things in it, one of which is the interface which was almost a clone of Gmail, i had no plan to switch to Google Reader as i was happy with netvibes but i faced problems with netvibes one of which was slow response and very tight space for the RSS. Also they loaded all rss feeds immediately so a person like me who is subscribed to almost more then 250 RSS  feeds its difficult for the netvibes to load up all my data in one go. So i switched to Google Reader which is now i think far more better then Netvibes.

So far the evolution of Google RSS feeds do look kool, but i hope that they work on implementing the a ranking system for the feeds as well on the basis of no of subscribers, quality of content and ofcourse with this a RSS feed search engine is also essential. Ads are already pulling up in feeds via feedburner and i hope they dont put up more ads in the RSS Reader.

Another concern is that the RSS feeds are a one way traffic could it be possible to make it a two way traffic, can RSS communicate back to the publisher with comments ?
