Google Reader is following in the footsteps of Gmail, Docs, and Voice with a clean new interface, that's easier to use and contains integration with the Google+ social network.
If you use Google Docs or the new Gmail preview, you'll be very familiar with Reader's new interface. Everything is very white and clean, with a single search bar across the top and red buttons to denote the service's main features. Reader has also replaced "Liking" a story with "+1", and when you +1 a story, you have the option to share it with any of your circles on Google+. This replaces the old "following", "friending", and "sharing" features of Reader and rolls them into the new social network instead. Head on over to Google Reader to check out the new changes, or hit the link below to read more on Google's blog.
Note that the new interface is still rolling out, so if you don't see it, check back periodically throughout the day. Google says everyone should have it by this evening.
