@bradenslen I looked through that giant feed which you described as a firehose, which it certainly is. Oddly, I didn't see Dave Winer, even in the Bloggers section. Maybe there's a story behind that.
@Ron Doesn't anyone worth their salt have scripting.com open all day in its own browser tab? ;) Separately, but somewhat related, that big firehose OPML feed also has lots of private feeds hiding inside of it that aren't public facing.
@c Aha, that story makes sense! That's in fact what I had until 2018. The firehose was so big that I thought it intended to be all inclusive, but it makes perfect sense to just leave Winer open to see the updates as they happen. Thanks for clearing that up. :)
@AndySylvester If you go to @c 's Following page and scroll way way way down to the end you will see OPML files.
@Ron thanks for helping me see that Chris Aldrich has the big OPML file referenced in this thread.
@bradenslen found it, thanks!
