Re: BitcoinTalk expert list. Who uses the badge.

I believe and can say for sure, you should add -ck (Con Kolivas) to Bitcointalk expert list. Wikipedia link:

https://en.wikipedia.org/wiki/Con_Kolivas

Maybe. His Wikipedia page has nothing to do with the Badge that is being talked about here.

Those Wikipedia just one of reference, but I think it related.

Development of the cryptographic currency mining software CGMiner

At least related to a few people that were written by OP.

I think this thread would be help (can be one of reference): https://bitcointalk.org/index.php?topic=557991.0
