Friends, if you haven't already, it would be a big favour to me if you could enable tags.pub to boost your public tagged posts.

Just search for @_followback in your Mastodon UI. Click the follow button there. (Don't try to follow from the profile page; it doesn't work yet.)

It will follow you back, and when you make a post with a hashtag in it, the server will boost your post from the appropriate hashtag.

#tagspub #hashtags #activitypub

@evan Is there a reason to do this when we can already follow hashtags?

@mayintoronto one reason is because your friend Evan asked you to do it as a favour.

Another reason is that when you "follow" a hashtag in Mastodon, it only filters the content that got to your server for other reasons.

There are three ways that content arrived: either you follow the author, someone else on your server follows the author, or your server is subscribed to a relay.

tags.pub lets you follow a hashtag globally, not just filter what got to your server.

@evan ah, so this would help a lot with say, @introduction for unfederated single user servers.

@evan @mayintoronto

This gives me the heebie-jeebies. "Global" makes me uncomfortable. Automatic boosting makes me uncomfortable. Both are not particularly Fediverse-type concepts.

Here's the intro page on this (note that Social Web Foundation lists Meta and Auttomatic as partners):

Sorry, Evan, but no thank you.

@jakebrake @mayintoronto Hey, Jake. Your concerns are justified! It's never a bad idea to look at projects carefully.

tags.pub is one of the oldest projects on the ActivityPub network. It was one of the test implementations of ActivityPub. It's been dormant for years; we've been lucky enough to get to implement this with funding from the Sovereign Tech Agency.

The service is opt-in, either by user or by server (and users can opt out if their server opted in). Nobody has to use it.
