The concept behind Googalyzer is interesting, though it’s probably not for everyone. It’s basically an open-source, tabbed web browser with built-in note-taking, web-clipping, outlining and bibliographic tools. The idea is to consolidate these different aspects of web research into one application.
This way you can have multiple research projects with all the relevant information kept in one place, without getting data from different project intermingled (this reminds me of the thinking behind Panic’s recent Coda web design application). If you do a lot of research online, and are not already using something like DEVONthink, this might be worth a look.
Googalyzer 3.0 beta 1 has just recently been released and is a free download from Funkware.
