I seem to be on here as soon as you have a question :) You can follow anyone you want, but since you asked for my advice, follow for follow is stupid. Don't follow bots. Just because someone follows you, doesn't mean you have to follow them. I see no benefit in having non-beneficial posts clog up my feed. I follow people who share the same interest as me and engage on my posts, as I try to do with theirs. Since your new, I would highly advise that you have your 'posts' take a back seat, and build up your following by commenting on other peoples posts. I equate a new steemian busting out a bunch of great content to a concert violinist playing in front of an empty orchestra hall. It might sound amazing, but no one is going to hear it (read it, in your case). So engage with other people and don't expect success to happen over night.

Cheers!
