The Internet being what it is, it’s useful to have ways of sorting all that information. To be able to get at it later, easily. First there was Furl, which I’ve used in the past and loved, then there was Yahoo!’s My Web (which is my current default choice), and now there’s Google Notebook, which is nifty for its own reasons.
All are excellent resources & tools, it’s just a matter of figuring out how to use them. I’m leaning towards MyWeb as a sort of all-purpose information sorting tool, with Google Notebook as a more project-specific tool. (Furl is arguably the most powerful of the bunch, but I haven’t yet figured out the best way to make use of it, sadly.)
