Discoverability was largely the reason why I got in fights with Mastodon users over the platform being in a bad place when Twitter had its first wave of musk awfulness.
I find that the system is now much improved, but man, I can’t stress out just how bad an impression I was given that everyone seemed to think searching posts by tags was a bad thing, and that tags in general were, in fact, objectively broken at the time. Like, people go on social media with purposes in mind.
It’s fixed now. Tag activity is shown correctly. Tag history also gets shown correctly. You can also follow tags. That’s all I wanted, and acknowledgement of it, not a philosophy discourse.
