Bridgy Fed syndicates new posts on this site to the fediverse; certain types of fediverse account can interact with these. If you’re on e.g. a Mastodon- or Misskey-based server you can search in your client for @tre@tre.praze.net and you should be able to follow/repost/reply etc; if that username doesn’t work, you might have more luck with something like @tre.praze.net@web.brid.gy … or maybe @tre.praze.net@tre.praze.net?
On the fediverse, I’m @tre@praze.net. My public profile shows some posts, but to subscribe and see everything (notably, boosts) you’ll need to search for my username in your client. If my account doesn’t show in the results, we’re probably not federated with your instance; hit me up and we’ll get it sorted.
My fediverse posts can also be followed via RSS, here.
