I flagged it because every comment I read on it was stupid. There was nothing intellectually curious about the topic-- just poking people's political identities.

Here, someone in close proximity to a reasonably significant historical event used social networks to broadcast his observation of said event. If this has happened before, it hasn't been very many times, and it's undoubtedly been only quite recently. We are witnessing a new historical phenomenon that will undoubtedly be worth a line in a history textbook.

Moreover, importantly, the comments on this article don't completely suck. There's some meta-noise like this, but much less complete political stupidity.
