The process so far
  The list was started by Jesse Grosjean of Hog Bay Software, as part of the development of his Bike outliner for the Mac.
  I, Dave Winer, offered to transcribe the list and provide a means for it to grow here on opml.org.
  This page is of course an outline, so you should be able to open it in any of these outliners. :smile:
Notes
  So far we only list editors, but there are tools that consume OPML files, databases and renderers, and I want to list those too. If you have any to suggest, use the process outlined below.
Additions, questions, comments
  Post a note to this thread:
    If you have a product to recommend for this list, please post a comment in the thread. Include the name of the product, what platforms it's available on, a link to the product page, or (better) a link to a page that explains your OPML support.
    If you feel that a product listed here does not support OPML, or if there are issues with its support, let us know.
  I want to keep this list up to date and accurate, but there are always time constraints, so I can't guarantee that all suggestions will be incorporated.
