I’ve followed all the frequent posters on piefed.social using my mastodon.social account so we should be seeing a lot more PieFed content showing up there now. But unless you use hashtags, I’ll be the only one seeing it!
When making your post, put a few words into the Tags field below the Body field, separated by a comma. No need to include the # character.
One more little bit of feedback:
I still can’t figure out how to get images in the body of my posts to show up on M, so I think maybe I’ll only add tags when a single image is shared, in future.
TBC, the multi-image posts frankly look terrible on M, full of empty space, and with unwanted formatting issues.
