Hello /c/Eugene! I’m so happy you exist!
The Fediverse has this awesome ability to allow for “listening” for relevant content via tags. I’m not sure how Lemmy handles it, but on Kbin you can set your magazine (community) to look for certain tags and it will pull in content from the Fediverse that has those tags. Also, if you add tags to your posts, they will possibly get picked up in various places looking for the tags. So please tag your content if you want it to crosspost passively.
Here’s a FAQ (for Kbin) that talks a bit about how tags work.
Kbin lets you see content based on a tag, as well:
(https://kbin.social/tag/eugene)[https://kbin.social/tag/eugene]. Just replace “eugene” with the tag you’re looking for. It’s helpful if you want to see if a tag is used and to discover where it’s used.
Please do say if Lemmy has similar resources or instructions.
