The post isn't making anything, it's just sitting there being read by us. The author, however, made some good points in the post. Additionally the verb to comprise isn't suitable here either, so it's going to sound awkward no matter how you try to rearrange the sentence. The "composed of" or "consists of" alternatives mentioned in the original page aren't really a good fit either. There's no need to complicate things: this post contains many good points. In truth if someone said or wrote any of these sentences, I wouldn't mind whatsoever. I know exactly what they meant and that's what matters. However since we're having a bit of fun, I figured I'd weigh in :)
