google  notes has some nice features including collaboration among multiple users, a publishing feature, integration with Google Bookmarks, the 'Unfiled bookmarks' link on the left sidebar of the Google Notes Web interface that sorts and displays all the urls you have saved, quick clippings of Web pages with the 'star' button, and the export to Google Docs feature.

ubser notes works in the same manner as Google Notes. However, one neat feature here is that you can add your tasks in any note that you are working on. Later, you can view the 'Open Tasks' link on the sidebar of the UberNote interface to open all notes with incomplete tasks. Similarly, you can integrate your bookmarks with any note and find it later with the 'Bookmarks' link. Other nice things to know about UberNote are that it runs on AJAX and has a history feature that will save all the revisions you make on your notes. You can clip notes with the UberNote online dashboard, with the browser extension, email your notes to a personal email address, or from an AOL IM application.
