Before everyone gets up in arms... how do we know this was an April Fool's joke and not an unfortunate glitch? All I'm seeing is this website calling it a joke with no real justification. Secondly, I'd be curious to see the intraday charts for the stocks that were purchased, just to see the effect this may have had. Thirdly, everyone knows that Zecco sucks and if you want a great social-networking broker, go with TradeKing.
