Google Shared Stuff

Am I missing something, or has Google just reinvented something it's already created?

Google has quietly launched a new service called Google Shared Stuff, which allows you to share links with your friends and others. But what I'm already finding confusing about this is that it doesn't appear to integrate with Shared Items from Google Reader. This seems like the most obvious thing that it should do - but as far as I can see, it's not there.

Apparently it's all part of the Google Moka-Moka project, but it's deeply unimpressive as a tool so far. Then again, I was deeply unimpressed with Google Reader, too, and now I use it every day.
