Should we allow question about the developers? Where do we draw the line?
In my opinion, a security relevant and trust demanding software like bitcoin, justifies that questions about the developers are allowed.. So I'm in favor to allow questions about the developers, if they
- don't provoke an debate, have an clear answer
- are related to the development somehow
- don't get to personal
I certainly agree that questions about the devs should be allowed, but only to a point. If someone really wants to don the tinfoil hat that is their prerogative, provided they do their own research somewhere other than this site.
The question you cited in your question was closed not because it is irrelevant or because questions about the devs shouldn't/can't be asked but because it was a duplicate. Perhaps not an exact duplicate, but this specific question is a subset of another question requestiong Satoshi's bio. This question should have been posed in the comments on the original.
Per Robert Cartaino (one of our SE-supplied mods, until we elect our own):
It's off topic. This site is about Bitcoin. It doens't need to become fodder for Who-is-Satoshi-Nakamoto trivia. Any biographical information you feel the need to expound on can easily be contained in the other thread. No need to perpetuate this this content of dubious value through the site.
Questions about the developers are some of the most frequently asked when I talk about Bitcoin. Closing threads of this nature only prolongs the amount of time it takes for people to find answers...
It's counter-productive to obscure this information when it is one of the most commonly asked questions!
Flow is right. Bitcoin is highly dependent on the skills and ethics of the developers. Questions that are otherwise on topic but also relate to people like developers who have significant influence over bitcoin should not be arbitrarily ruled out. Linus arguably has less influence over the Linux kernel than some of the bitcoin committers do over bitcoin, since only a small percentage of Linux users directly run the actual "mainline kernel".
But of course we should be careful about how such questions are worded.
Re: David's recent question - https://bitcoin.stackexchange.com/questions/1274/is-this-google-account-the-real-satoshi-nakamoto - I voted to close, I think this is getting a little close to speculation and irrelevance. Especially when it is clearly just a troll account.
