There is no way to figure that out. What I can say is that if a person that post needs to comment on at least a few of the comments they receive, not all but a few at least to let people know you read their comments. Most votes on post are auto votes, people don't read the post.
There is however a growing community of people that post and vote and comment. By going to other post and content you enjoy and seeing the comments and adding to the comments can and do create a network effect. People will see your name, eventually they will go and take a look at your page, at some of your post and may read and comment on them.
To gauge if your post are worth engaging you need to see what post in the same general area you are posting in are like that get a lot of comments. People have all different kinds of taste and likes, find some like minded people to comment on, and they will comment on yours.
