He's mentioned it before on several occasions. To be honest it's more than likely due to the fact it doesn't generate the comments, followers or exposure the more traditional platforms do. Outside of that Dan isn't one to interact when he does get a comment, to me it would seem if you don't interact you don't grow, at least here, I've never viewed what, if any, his participation on traditional platforms is. With the grand finale being that here it's not just if you don't interact but you don't upvote and reward comment content which I haven't seen him ever do, he evidently isn't into sharing the wealth.
