This is not completely clear to me either. When a post of yours is new, people can see it by searching for new posts. Also, as you said, people can see your posts through the tags. Finally, your followers can see what you have posted, although the way this works is a bit vague, since I am your follower and only some, not all, of your posts appear in my feed. If I want to see all of your posts, I have to visit your blog page.

I see... Difficult to master this smart steemit for me :)
