Is this a common occurrence?

Yesterday I published a post. It didn't get many views (7 at time of writing). That's fine. Par for the course. I would like more people to read my posts, but I'm not eye catching or interesting enough, I get it.

However, I gained 84 followers. My daily average follower increase is 0, so I'm pretty sure the reason is that I posted.

So I make a post, 84 people see I made a post and followed me, but didn't read my post? (Or bookmark it for later)

Why are you following me if you don't want to read my posts? What do you get out of this?
