Race, Class, App.net: The Beginning of ‘White Flight’ from Facebook & Twitter?

"to be fair, this piece is a speculative article. my aim here is to raise questions & start a conversation, not to make a pronouncement on what app.net will or will not be (because i don’t think that’s predetermined, or something we can know yet). there’s a reason there’s a question mark in the title."

I feel that not making herself clear in the article is deceptive. I had to read the entire article to figure out there's nothing there.

[Edit] Furthermore: with Twitter's follower model how much more segregation can you get? How can you compare white flight from neighbourhoods with white flight from Twitter? What are they running away from if they choose whomever they follow?
