Agreed - on the whole, I think this sell-off is a good thing for bitcoin.
If you were an early adopter, and were looking to maximize your cash-out value, what would you do? I'd do something like what's been happening over the past few days, with sell-offs in stages: a big sell-off to 2.50, a stabilization time, a sell-off to 2.20, a stabilization time, and now a sell-off to 2.00 and a stabilizing time. Perhaps he will go another round to 1.80 or something - no way to know. But he's selling many coins, and for cheap, redistributing them in the process, and at the price others are willing to pay (ie, fulfilling orders on an exchange). A sell-off is better to do now than later, when there will be more vendors actually using btc.
After collecting most of the cash from the exchange, many more people are then holding btc, and are more likely to try to spend them other places. And speaking of which, I just received my first product order using bitcoins in the mail today, some packaged food that was actually cheaper than any of the nearby markets even after including shipping.
