If you do set up an OPML file for your Domains ’17, let me know. I’d love to subscribe to it!
If you want to take it a step further, you could consider making an open OPML file of the people you’re following from a conference like Domains ’17. Much like Twitter lists, these are sharable (so others don’t need to build them by hand), or more importantly for Feedly importable! Some RSS readers will also allow dynamic updating of these OPML lists so if someone is subscribed to your list and you add a new source, everyone following the list gets the change. I’ve written some thoughts relating to this with respect to the old school blogrolls and included an example here: http://boffosocko.com/2017/06/26/indieweb-blogroll/
