Actually, Instagram turned out to be a fantastic deal. Many thought it was over-valued at the time but Instagram has passed 100 million active users early this year and users spend more time on Instagram than they do on Twitter (or practically any other app than Facebook or email). In retrospect, I think $1 Billion was a steal.
