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.
I have heard of the opposite. Mastodon users can see and comment on lemmy posts, but i have yet to discover how to view mastodon post from lemmy.
If it is indeed possible can you or anyone elaborate how to?
The mastadon user posting the thing needs to tag the Lemmy community in their post and then it will show up like any other post on Lemmy. You wouldn’t even know it’s from Mastodon unless they said so in the post.
You can usually tell it’s from Mastodon because it’s got a couple dozen hashtags scattered throughout the post and a dozen more users and communities tagged.
You have misread their comment and understood it backwards. AP’s saying people on Mastodon are engaging in Lemmy discussions.
There is no way to follow Mastodon users from Lemmy. Lemmy simply does not work that way.
Hrmmm… at a (strong) guess, PieFed does. You can follow anything, like a community, post, comment (even ones you do not own), or a user account. You would get Notifications triggered every time they post something, I believe. Including comments as well as posts, but again just a guess.
It’s a great way to follow a low-volume something or other! At higher volumes… it can get a bit much, but at least the tools are available, and you can always wipe all Notifications at once if need be.
The post you’re commenting on was made on a selfhosted instance of akkoma.social, so federation across softwares definitely works.
