Both? Most successful blogs and news sites I've seen tend to have multiple ways for their audience to contact them. Usually comments for posts plus accounts on various major social media sites and some sort of chat feature (for gaming sites nowadays it's often Discord, though it could be a forum, or Slack or IRC). Of course, you then have to strike a balance between getting setup on every platform under the sun (and spreading yourself too thin) or putting all your eggs in basket (and depending too heavily on traffic from a single source or platform). But yeah, there are usually multiple ways for people to contact successful blog authors.
