If the majority of people actually gave a shit about any of the things you mention (which they should) then they would have all personally asked mybitcoin about such things before putting their money into it. They did not.
Far too cynical.
As a group, we can monitor what's going on in order to inform the herd.
dacoinmeisters thread, asking all of the exchanges about how their bitcoins were stored and managed, was valuable. Now that I know that mtgox has 98% of bitcoins stored offline, I have a lot more confidence in them. I wish someone had asked the question of mybitcoin. All of these efforts help.
