A few months ago I started sharing items through google reader. It saves a lot of time if you just want to share some link you obtained through some rss feed, so you don’t need to create a post for that.
Tonight I noticed Google launched some kind of integration layer for that. So from now on, you can see my recent shared items in the sidebar. 🙂 It looks like the “read more” link actually provides a separate RSS feed which you can subscribe on if you don’t use Google Reader.
