What's Popular tie-in with Google Reader

Google recently launched, "What's Popular" for iGoogle. The gadget is being touted as a Digg-clone with users being able to submit and rate articles, etc.

What's disappointing is the lack of tie ins to other services at Google. How good would this be if it was part of the blogger toolbar? Google news? Google search results? and dearest to my heart, Google Reader? What is users could just click, "Share on Google" for anything and it gets automatically entered into the Google products through intuitive tie ins? I'll keep my eye on this, but I'm not optimistic that I'll see anything soon. Most telling? The fact that the "Share this gadget" link tees up an email to friends... really?
