I really don’t like automated email. There are now a couple Discourse forums which have sent me digest emails that I’ve had to unsubscribe from. I’d really like to subscribe to them, but I can’t handle the information overload.
Another way to have a manageable RSS feed is to only send me things which have reached a certain level. I have historically set up RSS feeds based upon API integrations, so I had an RSS feed for reddit posts which hit X (e.g., 500) points. Maybe I’ll try doing that with Discourse at some point.
