Wikalong looks like a real Next Step on the web. I have to figure out how to setup a private wikalong server. I also want to tell Jon Udell about this AND tell him its time to fix is blogroll link to point to jonschull.blogspot.com.
I also need to remember to track a suggestion I myself made using wikalong that it be used to create a dynamic map of frequently travelled by-ways in cyberspace... That idea, and some already-underway discussion of it, is at http://wikalong.phunnel.org/kwiki/index.cgi?WikaLongByWays
"Wikalong is a FirefoxExtension that embeds a wiki in the SideBar of your browser, indexed off the url of your current page. It is probably most simply described as a wiki-margin for the internet.
One general difference in the functioning of the wiki you may find is that wiki links would be external, as opposed to traditional wikis which are more internal link centric."
