The first Radio was Radio UserLand released in 2002. The second was Radio2, a server-based linkblogging tool that ran in the OPML Editor environment. Until last Friday I did all my linkblogging in Radio2. Radio3 is a browser-based JavaScript app with a thin server that runs in Node. The 3rd Radio is by far the best, but of course I’m biased.
