The big difference? Mircea's & MPOE-PR's behaviours don't affect the amount of money I make, nor the value of the assets I'm holding. On multiple occasions, nefario's behaviour has lost me money.

As a matter of fact, I've seen mircea on IRC quite a bit lately. Looking through the logs, he appears to be his normal (asshole) self...but, despite that, it appears MPEx is making more and more money.

In my experience when someone with greater technical or financial skills point out errors in others' works, they take offense. After repeatedly pointing out the same errors, the person with experience tends toward impatient, as he or she knows that the only reasons for repetition of error is either incompetence, or criminal intent. When the person with skill points out incompetence, or criminal intent with impatience, invariably, "asshole" is the description.

By the above logic, I believe, you're correct in stating mircea is an asshole. And this is why I sent him 20BTC....I paid that for risk avoidance (well, and some lulz now and again)

Money well spent. Come to think of it...I pay Mircea to be an asshole. He does a great job

See, and now nefario is trying to legitimize his platform, but he's ignoring the people who've brought his platform to be what it is, and, judging from the number of people I've seen withdrawing money, and bailing on GLBSE, that's not working out so well for him. But, then....he caused values of shares on his exchange to drop in value through his personal actions (which do not enjoy the support of all the GLBSE shareholders) I can only see this as the actions of an ass. And that's not who I want holding my wealth.
