After much consideration I have decided to participate on it.
Maybe many people won't, I donno, but I think it is a good initiative.
An advice to anyone that doesn't feel like they should do it for whatever reason... I have one additional argument to try convince you:
If the initiative gets enough following and you have the bad luck of having some of your bitcoins on custody in an exchange involved in some sort of fractional banking you will probably lose your bitcoins if they run out of them and you are still there before everyone wanting to participate finish getting their bitcoins out.
Also, don't wait until the last days to do it. Don't be the last guy there risking your bitcoins.
Don't say I didn't warn you

Like you, initially, I was disinclined to participate in this particular event because I already have various systems in place that I have honed over the years, including buy/sell orders that are already established under my system.
Nonetheless, I have decided that I am going to participate too, but surely 100% will not be good for me.
I am going to engage in some incremental participation that causes me to move some funds off of each of the exchanges in which I hold bitcoin, but also contributes to the cause in other ways from my own perspective. I am not sure about which date I will move my coins, but I am not averse to moving some of them on January 3rd because that is supposed to be the "stress test" date, but it might also be good to move some coins ahead of time, like you suggest, bitserve.
