Today Google announced a new service called Google Notebook, which they're touting as a research tool. It allows easy clipping of web page content onto a virtual notepad, and then adds the ability for the notepad to be published. Add RSS feeds and run Google ads on the side, and you almost have the entire feature set of Squidoo. Well, maybe not the entire set, but it's interesting to see Google make these small moves into other people's turf. Google co-op for example is running in competition with many vertical (topic-specific) search engines, and Google pages is running against Yahoo! Geocities and to a lesser extent MSN pages.
