As always with HN posts titled like this, the answer is "No."

I'd support a change to auto-kill submissions that end with '?'. If you can't say it as a declarative statement, it's link-bait.

  Social media use in Indonesia predicts Facebook's decline

"it's link-bait"

QED

But this entire post was clearly an honest question. And a good one.

I am an indonesian who lives in US. You are half right.

The problem is that internet is scarce and they rely on mobile phone for almost anything, which explains why RIM is doing so well there (Blackberry Messenger package bundled in their phone services)

They are used to short messages like twitter, sms, bbm. No, facebook's decline is not the case here.

Twitter seems to be quite dominant overall in Asia, possibly for cultural reasons (Facebook is such a western-thought design). In Japan for instance Twitter took off long before Facebook did, and is still much bigger today.

Hopefully.

Well all this assumes that Facebook just stands still. Which given all indications isn't their style.
