I'd consider getting in, maybe at around $10-$15. Even then, I'd like to see a better explanation of their revenue stream model for the future than what I've seen so far. I think their estimates of growth in brand advertising revenue is exaggerated, and other streams such as FB's virtual "currency" for on-line gamers is highly speculative.
That’s a pretty good take. What is the typical P/E for this type of business?
