Yahoo adds Webrank–what’s next?

Yahoo’s launched Webrank, a new page rank tool similar to you-know-who’s that is visible from the Yahoo Companion toolbar.
Now that they’re getting skin in this (search) game, do you think that Feedster or Technorati will soon announce a partnership with them?
After all, isn’t the new mantra “S/he who I(semi)structures all the data, wins?”
