Aswath Damodaran's Twitter Valuation

Having learned from the Facebook fiasco, I  expect the bankers and the company to make the Twitter IPO a smoother offering. That process will of course start with the road show, where they will package the company like a shiny new present, and unwrap their “offering” price. I am sure that Goldman’s bankers, working on this deal, are a capable lot and will price the stock well, with just enough bounce to make those who receive a share of the initial offering feel special.  As I watch the frenzy, I have to remind myself of two realities. The first is that there will be lots of distractions (like this one) during the IPO, most designed to take my eye of the ball. The second is that the bankers have their own agenda, and I cannot make the mistake of assuming that it matches mine. Watching out for my interests, here is how I see Twitter: at a $6 billion market cap ($10/share), I think it is a very good deal, at $10 billion ($17.5/share), I am indifferent to it, and at $20 billion ($35/share), it is a moon shot. Could I be wrong? Of course, but I would rather be transparently wrong (hence the long blog post detailing every assumption that I made) than opaquely right. I welcome disagreement (though I would much appreciate your phrasing it agreeably).
