David, not sure how I’d missed your note originally, but a copy of the webmention just bubbled up for some reason!
I do use Woodwind occasionally; though it was often down or had issues it’s been more reliable in the past few weeks/months than it had been in the prior year. I love the fact that I can use its interface to reply and react to posts directly.
Just a while back I’d written some thoughts on feed readers in general, but I also covered some interesting portions of Woodwind if you still haven’t had the time to check it out: http://altplatform.org/2017/06/09/feed-reader-revolution/
