Interesting news I collect via error500.net where he tells us is that of Google NotebooK.
Now Available Google Notebook, the new invention for “annotate” what we will looking interesting for web browsing.
Is discharged in the form of browser extension, Firefox versions 1.5.* (I'm not having worked 1.5.3) and Internet Explorer. Mac users will have to wait, only input support for Linux and Windows. If you want to take a look, can be downloaded from Notebook download.
I just played around with Google Notebook. You can mark text and save. You can have more than one “notebook” to separate by theme and soon there will be a search (Still not working!) to pry into their own and other notes (that are public).
A success of Google Notebook is that it integrates quite well with the browser (I've only tried with Explorer) and site interface is quite maja. Apart from this, as a regular user of del.icio.us, I am not making me this new way of marking. Has no tags (add no semantic) and at first glance I think I'll take any bookmarking service “traditional” (all traditional services may have a couple of years) that lets you store the annotated web content. In any case, will have to play around with this to see all the possibilities
