I was searching the web tonight for “Zope” (something) and I stumbled upon a site called StumbledUpon that records interesting pages that other users have stumbled upon and lets you sort the web accordingly using a browser plugin that works in IE and Firefox. It turns out that a whole lot of other people have also stumbled upon this site because a search result of pages tagged with the word ‘zope’ gave me back comments from at least 20 other “stumblers”.
