The follow system is nice and all, but it requires too much effort to scroll through that giant activity page. I think we should get a different coloured notification (preferably rainbows, because it's so important) whenever a followed user does something. And whatever happened to the "Last Active on..." area on the profile page? How am I supposed to stalk people when I don't even know if they've been on in the past 24 hours? I suggest you bring back that feature, as well as add a friend system for bnet alone. Followed users automatically go into your friend zone and you can see a little rainbow coloured circle whenever they're online, for maximum stalking capabilities. Also, as far as I can tell, that blue bar next to threads just means that a followed user created the thread. If any followed user so much as posts in a thread, the entire thread should flash rainbow colours and clicking on the left side of the thread takes you directly to the followed users post. If multiple users posted in that thread, then it opens multiple tabs.
Feel free to make moar stalking suggestions in this thread!
