yes

I think that in order for it to effectively we would need to get moderators of sub’s onboard. They can sticky posts keeping them from getting lost amongst everything else maybe get involved with moderating the community on Lemmy.

Some subreddits might flag too much Lemmy promotion as self promotion or spam unfortunately.

Not yet. But I expect Lemmy to be more mature, stable and have new features in about six months. This is going to be a marathon. Not a sprint.
