$1B seems high for Instagram. As I recall, Google only paid that much for as big a site as Youtube. Of course, I guess it's much easier to avoid losing money with Instagram- video streaming is really expensive, and Youtube lost money for many years.
Eh, don't be too surprised if Facebook's market cap goes to 200B, 300B+ even, before the end of the year.
