@smokey, @donmacdonald, @ron, @macgenie: @herself makes a good point about building culture. I mused about this a little bit. The way I see it, the culture that M.B is establishing is "online civics". Currently, the Twitter culture of "finding your people" is by clicking a Follow button. M.B compels a different civic behaviour: active engagement with "your people", even as simple as an emoji @-mention. Right now this recurring discussion of Follows/Likes is pressing on what kind of civic culture we want on M.B. I think time will tell whether M.B's current civic culture can, at best replace, and at worst coexist, with the civic culture ingrained by Twitter. The current takeaway message for me is: (1) culture can be a very fragile thing; (2) depending on their makeup, two cultures may not be able tocoexist without one capitulating to the other.
