You're just going to get buried in the rabbit hole.
What you want to do is to define your parameters:
How many hours can you put up with being distracted from family and community?
How long do you think the money you make should last?
How much loss of purchasing power and earning power are you willing to sacrifice for exchanging into fiat?
How much personal energy will you have left to be active in what you care about?
Work is worth what amount of time you have to put into it aside from other things you need to do.
Time is worth what you could be doing with it and how much more time that will take if you are distracted.
Money is worth whatever amount allows you to live at those parameters above.
Labor is a commodity. Work is not. Let's start acting like it.
Rather than suggested price, it should be reference price, window of variation that will not interfere with the above, the change in value of the fiat as well, and whether the price is moving in the wrong direction.
All this tweaking needs to include the tweaking by central banks.
And what we really need are trade recycling patterns. Using the same BTC 5x to buy a car by cycling them through the community. That's how you get stability.
Exactly:
"How many hours can you put up with being distracted from family and community?
How long do you think the money you make should last?
How much loss of purchasing power and earning power are you willing to sacrifice for exchanging into fiat?
How much personal energy will you have left to be active in what you care about?"

That valuation is going to vary widely.
These are the kind of questions one might ask when deciding whether to accept a job offer. The data I'm trying to come up with is a reasonable estimate of what that job might pay with a shelf life of more than 20 minutes. I also believe that if people are aware of a reasonable, expected average then they are more likely to trade around it. If you recognize what the current valuation of a commodity should be and see that it is actually trading significantly higher, you might recognize a bubble more rapidly and responsibly sell. Enough responsible selling will suppress the bubble without causing drastic market corrections. The same works in reverse - if you recognize that a commodity is under-valued at the moment, you would certainly be best served to buy some and then re-sell when it becomes correctly or overly valued again.
The big problem that I think we've come to an agreement on is that factors like MtGox's dark pools, unmonitored black/gray market exchanges and transactions etc. make it very difficult to determine proper valuation of bitcoin as an asset. Thankfully we all have the ability to peek directly into the block chain and attempt to extract data from the transaction database itself. This is what I'm currently attempting to do (or what I will be attempting to do once blockexplorer comes back up).
