To clarify, this isn't my service. I'm an early adopter, but it's created by Manton Reece. (Long ago he created a web service called "Tweet Marker" that a lot of third-party Twitter clients used to sync reading positions.) So I have no idea if it's going to go out of business in two years, although I guess I wouldn't really know that even if it was mine. :) Those are always the big questions -- is the service viable, and are you going to use it enough to make it worth it? (And those two questions are connected, since enough people have to say "yes" to the second question to make a "yes" to the first question possible.) I still use Twitter, and I use Mastodon, too, although I'm less sanguine about Mastodon than most of its proponents seem to be.
