I basically did the exact opposite. I never press the upvote/downvote button, but I almost always leave a comment on the page whenever I have something interesting to say. I even reply to the replies I get. I have carried this behavior forward to Lemmy.
This is just natural. You want to comment on threads to conversate, even if you don't really agree or disagree with the article. If you like/dislike the article enough, you'll up/downvote it and comment on it.
