My Facebook timeline has in past 8 months become full of irrelevant sponsored posts and ads but before that was not an activated global neighborhood posting on interrelated topics.

What's happening in Istanbul and Turkey and the Turkish diaspora around the world this week has made my Facebook timeline suddenly a relevant, activated global neighborhood.

I am seeing posts this week from contacts whose posts I have never seen in my TL. (Turks were early and enthusiastic adopters of FB so many connected with me back in 2007 as I told Intel Free Press here.)
I am seeing posts from people who are saying they never have posted on this topic before.
I am seeing groups of people I know from different locations, settings and times actively share and comment on a related set of posts.
I am seeing people from my high school trying to parse a topic that other people in my feed (people I've met over more than 10 years, some I worked with, others I spoke to their class, others I know socially, etc) know about intimately and are reporting first hand.

This week has been what Facebook should and could be to make it a place I want to go in the age of Twitter, but so far never has been.

This phenomenon is due to the severity of the news, and the fact that my network is seeded with a majority of people who care about that type of news.

If Facebook has been making the shift from social graph to the more valuable (commercially, and for readers) interest graph, this week my TL made that shift on its own.
