This will work like public Twitter profiles, where you can follow whoever you want, whenever you want. As a user, you can always see a list of who you're following, as well as a list of who is following you. When that user does something on the site like create a new forum thread or create new game content (ie a new castle in Sieger) or get a new achievement, you'll see it on your activity feed.
From this logic, it's assumed that anything "special" the user does will be shown in your feed. If they make a blog about their game, make a thread about their game, or update their about page, to me, I deem that important enough. So this will show up in your feeds, and you will automatically get notice of "Sonny 3 will come out in about a month!"
