Google Notebook Shuts Down

Why Google Docs is not a good replacement for Google Notebook.

1. Notebook you can tag entries in a notebook. Docs you can just tag the document. 2. You can view all entries by tag. 3. Notebook gives you a count of how many items you have related to a tag.

Why is google taking away something that I use almost more than I use gmail? =-(

Any good alternatives?
