The linkage of micro.blog to Mastodon has been fun to explore. I have not tried subscribing to peertube or any other non-mastodon activitypub services. Tempted but I’m not that much of a digital media consumer.
This micro-blog is linked to @Martyh on Twitter and to @marty@oldbytes.space on Mastodon. The latter is a bit of a backwater in the “fediverse” which means it doesn’t get overrun by too many messages coming on the federated timeline. It think that’s enough of a toe in the water with the IndieWeb for the moment.
