Google's appetite

Measure Map is a service like technorati; Writely is an online word processor. They are totally different from each other and have no relationship at all, right?

It is true a month ago, util Google bought both of them. And now, there is a tag appearing in both site:
"that's now part of Google."
Another common point shared by them is they are both in immigration process to Google system, and does not open registration now.
But they allow you to leave your email address to book a position when they open registration. Yes, this is what we met when gmail come.
What is the next one Google will take a fancy to?
