Obviously, we all have our doubts. You can never be 100% certain on the stock market, or anything in life for that matter.
The issue that we're faced with on this board is level of confidence in the company. It seems to vary widely, from those who (supposedly) have no confidence in this company and its initiative (eg Dennis, extra) to the supremely confident (eg King, High Potential). I'll admit that I'm on the far right (confident) on that spectrum, and have been from the very beginning.
Hopefully the confidence of those on the far right can remain unwavering for many years to come and others can join in on the euphoria... cuz it feels damn good not having to take drugs to fly high as a kite!
