Google has added the ability to share content from Google Reader to friends on Google Talk(or in other words Gmail Chat).

So, we've linked up Reader with Google Talk (also known as chat in Gmail) to make your shared items visible to your friends from Google Talk. Once you've logged into Reader and been notified of the change, these friends will be able to see your shared items in the Reader left-hand navigation area under "Friends' shared items". We've provided an option to clear your shared items in case you don't want your friends to see what you've shared in the past. We've also added a Settings page so you can choose which friends you see and invite friends who aren't yet sharing to try it out.

We're really excited about adding friends, but want to make clear that this is a work in progress.[Google Reader Blog]

How it works? You log into Google Reader and see a friends tab where you can now specify friends from your broader network (ie: Gmail/ GTalk contacts) to share items of interest with.
