Hashtags do not replace groups.
No one moderates them. They’re easy to hijack and spam. And there’s simply no permanence to them.
Which is why, if you actually want to discuss something, it’s better to tag a group. For example, if you want to be part of an actual PC gaming community on the Fediverse, it’s better to tag @pcgaming@lemmy.ca than #pcgaming.
This needs to be common knowledge because people new to the Fediverse do not know about groups. Hell, I’d say people who have had Mastodon accounts for years still don’t know. And that’s a shame.
@fediverse@lemmy.world
@Coolmccool@mastodon.au @fediverse@lemmy.world The best way to explain #Pixelfed is that it’s an Instagram-like front-end for the Fediverse. But practically speaking, it’s Mastodon if pictures were a requirement on Mastodon. You interact with a Pixelfed account from Mastodon in much the same way you interact with another Mastodon account, or how you’re interacting with my Akkoma account right now. It really is just like email.
Regarding group topics, the best way to find them is to do a search on a place like lemmy.world or lemmy.ca. For example,
uiux@programming.devis one. And you can find the URL here:https://programming.dev/c/uiux
