I try to engage with all kinds of posts as long as they have something to say, some trending, some barely viewed, some from people I know and a lot from people I don't. It seems to have worked, I managed 120 followers in 2 weeks after banging my head against the wall for the first week. The chat room is also good help. The better your comments, the more likely you are to bring people over to your page, of course, but it also has to do with timing, if you post a good comment early, it's more likely to get attention than if you post it later. I left a really awesome comment on a post today and got 8 followers from it.

There are users who spend a lot of energy promoting new users, I link to 5 of projects in this post https://steemit.com/the50/@whatamidoing/milestone-post-100-followers-settling-in-and-minnow-support-goups

I will follow you for some support. I know how it is trying to get heard, I was there a few days ago!
