Just noticed that Google Notebook pages have a PR 7 and links in them don't have the NOFOLLOW tag. Has anyone explored using Google Notebooks as a means of building links, or am I missing something here that would render them useless?
Isn't that a page you need to sign into with your google account. If so, spiders don't know your password.
Your actual notebook page would have PR 0. You would get better link building using forum signatures.
