By the way, if you’re not familiar with diigo, it’s a collaborative bookmarking tool available for free on the web. It fits in and becomes part of your browser so you can capture information of any kind (words, audio, video, URLs, etc.) while browsing, doing research, etc. So far I’ve just described bookmarking, which we’ve all been doing that since Internet Explorer and Netscape were duking it out in 1995. So what’s the difference? The twist is diigo (like many competing services such as del.icio.us, furl, spurl, Yahoo!, Windows Live, and others) makes your bookmarks available to all other users of the service, while doing the same for you. Instant sharing. Of course you can also restrict your bookmarks to a particular group or keep them to yourself. But where’s the fun in that?
