Google Notebook is live

http://www.google.com/notebook

There's an extension you have to download

System requirements:

• Windows XP or Linux (may not work with Mac OSX)
• Firefox 1.5+ (Internet Explorer version available here)

However, it installed fine for me (Mac OS X 10.4.6, Firefox 1.5.0.3)

You're supposed to get a "Note this" link in Google search results but I don't - maybe because it's Google.ca that I get, not Google.com?

It puts a "Open Notebook" button in the bottom right of the status bar, and adds a contextual menu item "Note this".

If you highlight some text on the page, it will make that the "note" and attach the page URL.

Opening the Notebook pops up a little window in the lower-right of your browser.  I don't see any way to resize it - you can just make it a bar, or make it fullscreen.

Here's a Notebook about Notebooks I just made.

There isn't really any concept of tagging.  You can make sections, that's about it.
The full page is Ajaxified, you can drag and drop notes between sections.
As soon as you make changes, they appear in the public version of the notebook (if you have made it public).

You can change the note after you have saved it, but you CANNOT change the link that is associated with it.  I wanted to change a long login URL that Yahoo made when I went to notepad.yahoo.com, but I can't find any way to edit it in Google Notebook.

Seems like a very dumb linkblog to me.  How dumb?  There is no RSS feed for the notebook, for one thing.  I have to say, I don't get it.  There is WAY better software (desktop apps or web apps) for this sort of thing available.
