I believe it's pretty intelligent for PayPal to integrate new potential currency exchange models into its continuum/plans. "Hijack" implies something stolen, which seems to me an incendiary overstatement of their actions here.
Just a thought.
However just sticking with that article, the interest as far as social media and competing technologies is there I believe, and the hacker news people can see through that site's very obvious bias and see the numbers and information presented.
Edited title anyways, I was just reusing from other sites, agreed that could have been submitted better initially, apologies.
