Laziness on your part? etc...
Just to be clear - I don't doubt your dedication or integrity for a moment. However this is the internet and so extreme caution is always best.
I'll emphasize that this project isn't about just me. I believe I'm qualified to make the contact and am happy to do so, but if I don't push this forward anyone else is free to pick up the slack. The rules for the pledge are fairly clear; and as a treasurer myself I am committed to properly use the funds I hold, however this proceeds. If we all forget about this thing and at some future time someone will want to take another shot, the funds will still be waiting.
Will it help if we rephrase it as two separate goals?
1. Get enough funds to credibly approach Wikimedia (tentative target: 200 BTC)
2. Get enough funds to convince Wikimedia (target: Unknown)
You may not yet have enough information to optimally contribute to the 2nd goal, but you can contribute to the 1st, also important, goal.
Sure - if you get some acknowledgement from wikimedia that they will agree to serious / technical talks if we can pledge 200BTC that's fine. If it's just a vague "I think this is enough" then I'll remain sceptical.
It's turtles all the way down. Quoting a number that will persuade them to have a serious talk is itself serious talk. We need to bootstrap this somehow. And whatever we do, some uncertainties are bound to remain.
One final point. Charity donation is more maleable that you are giving it credit for. Of course money talks, but it doesn't have to literally be cash undeneath someone's nose to have value. Being a respected representative of a wealthy community *is* tangible value to charaties - and they know this! Don't be afraid to talk yourself up!
I'll keep that in mind.
Wikimedia isn't getting jack from me until they accept Bitcoin.
Yes, that's the point. Collected funds will not be given to them unless they accept Bitcoin or need the funds to work towards it.
