More Facebook drama, this time from an interview with WhatsApp co-founder Brian Acton. What was most noteworthy, though was the response.

“The problem with focusing on features as a means of differentiation is that nothing happens in a vacuum: category-defining products by definition get a lot of the user experience right from the beginning, and the parts that aren’t perfect — like Facebook’s sharing settings or the iPhone’s icon-based UI — become the standard anyways simply because everyone gets used to them.”
