Google Notebook Ended

Google Notebook - is a free online application offered that allows users to save and organize clips of information while conducting research online.
The development of this service I have used some year earlier (2 Jun 2007 - This is what my last note on Google Notebook tell me). has been stopped. There is no new user signup but the good news is existing user can still use it. 
It has been a handy gadget while doing online surfing, but Google thinks that it is now part of good old days and they have to offer some new and enhanced products. This is what is listed as alternate to Google Notebook (-)
