Online notebooks revisited!

A number of companies have been working on developing online notebook. Notably, Google notebook is a good application for joting down data found while browsing. Zoho has also announced a notebook. Although not released, it's features look promising. Now, a new website skrbl has also come up with something similar. It does come with some difference -- you can scribble on the editable page. Unless they collaborate with some major web player, their applicability looks limited.
