I am only wondering, why all the bitcoin-media is not covering the shady history of this Brock Pierce guy?
Good question. Who supports that media, e.g. Coindesk? Not small investors, I would think... Perhaps some people with large MtGOX balances?

founder and owner of coindesk is Shakil Khan. He is invested in SecondMarket and BitPay. BitPay is a competitor to GoCoin (Brock Pierce). Although I do not think that there is real competition among the two, because Pierce´s investments seem to focus primarily on asia/china (KnC-miner, Robocoin).
I found this site:
http://www.coinsumm.it/Among the speakers are Brock Pierce, Shakil Khan and Roger Ver. A lot of other "Angel-Investors" will also speak there. So these AIs maybe belong to the same network (more or less) and do not want to hurt each other too much, because it would negatively affect the group?
One thing is interesting though: Above each speaker´s name is a photograph, but the picture of Pierce is not a photograph.
There's a Michael Jackson and a Johnson pic. Perhaps, he felt he couldn't compete. Besides, he's the only one in the group that has his likeness on physical bills.
