Using tags on our posts and training new users to search with tags, might help them find people that interest them and when they find interesting people and engage with them, then those people engage back.
Too often those of us who have been here a while, have curated our feeds to the stuff we like and don't regularly go looking for new users to follow.
People used to use the #grownostr tag for non-bitcoin stuff and it helped people find content to follow. Maybe we should get back in the habbit again.
