My ideal is a personal website where I write everything, including long-form articles, short statuses, and replies like these. Folks can then find me via a single identifiable address and then subscribe/follow the entire firehose of content or choose subsets according to post types, topics, or tags. They’d then be able to reply or react on my site or their favored platform, which my site would collect regardless of origin, with subsequent replies and reactions getting pushed out to them. Oh, and it should work with both ActivityPub clients and servers, IndieWeb sites, and syndicate/backfeed to other social networks either with or akin to the Bridgy service I mentioned above.
Amen !
