... too funny.
In all seriousness, we have had some progress:
MyBitcoin was an excel spreadsheet on some anonymous guys laptop
Mt. Gox was a web based exchange written in PHP by some tubby french guy bouncing on a Swiss ball nursing a frappucino
Bitfinex was web based exchange written in Ruby by some HK hedge fund wannabes
... continuing on this evolutionary arc next we'll have the new 'biggest' bitcoin Javascript-based exchange blow-up, then a java-based exchange, one day some real coders and security guys will decide to start an trustless, dark exchange because the financial shilly types, lawyers, regulator parasites and govvy agents have been run out of town with bigger problems (of the lamposts and nooses type)
