@darius let me think about it a bit, when I read the wiki link I liked the 'friends' concept. that is what clicked for me, before that I couldn't figure out what was 'exclusive'. 'friends' is the key takeaway here, something personal. I will try to think of something.
@d3cline Yeah. The thing is it's not about friends necessarily -- I also use it as kind of a quarantine zone for accounts that post too often but I still want to follow occasionally.
