The second, related concept, that I've been turning over in my mind is that of the variable, socially constructedness of time. Eviatar Zerubavel has written a lot about this. Most notably, in my opinion, is his Seven Day Circle, about the social construction of the week.
The third concept, not surprisingly, is about hate groups online and the way that time has begun to speed up both the proliferation of these groups (or at the very least, their websites) and how that fact affects both the analysis of these groups and the praxis of doing anything something about them.
No answers or great insights, just thoughts to ponder at this point.
