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 @evan @mayintoronto I'm with you. No thank you. People can follow hashtags. Nobody is following the accounts that are set up to echo hashtags. It's a waste of bandwidth.

@mlanger @jakebrake @mayintoronto

You can definitely opt out of tags.pub! Nobody has to use it if they don't want to.

You can follow hashtags in Mastodon; many other servers on the Fediverse don't have that feature.

When you follow a hashtag in Mastodon, it only shows you content from people you follow, or from people who others on your instance follow. If someone posts on the Fediverse using a hashtag and nobody on your instance follows them, you won't see it.

@mlanger @jakebrake @mayintoronto you're right that there are very few followers for the hashtag accounts on tags.pub. We are just getting this service started.

We're actually pretty careful with bandwidth.
I am one of the authors of ActivityPub, and I wrote a programmer's guide for O'Reilly Media about the protocol. I try to use it as carefully as I can.

If nobody's following a hashtag account, no data gets delivered.

@evan @jakebrake @mayintoronto Yet every single time I use a hashtag I get a notification for each hashtag. Your system is obviously creating accounts for each hashtag.

I honestly don't understand why you think this is necessary when one of the benefits of mastodon over other systems is that you can easily follow hashtags. You are attempting to solve a problem that does not exist. (1/2)

@evan @jakebrake @mayintoronto Also, what you say is true, following hashtags does not do what everyone says it does. I was led to believe that following a hashtag would show all of the posts containing that hashtag, regardless of whether other people on my instance followed the account posting it. It seems to me that the current set up puts small instances at a disadvantage.
