Quick too for nerds: OPML editor (Mac, Win), developed by Dave Winer:
The core purpose of this program is to create outlines and share them with other people, in various forms. 1. Choose the New command from the File menu. This creates a new outline window. 2. Type: Now is the time for all good men to come to the aid of their country. Save. Navigate to My Documents, then OPML, then www, and save the file as test.opml. 3. Now switch over to your web browser, and enter the url of the file, and see if it opens.
Why do I blog this? because it's a tool I will use to play with my OPML files.
