Here is a scary thought for you.

The faith of billions of euros(or dollars or whatever currency you prefer) are decided by Excel sheets with quick n' dirty VBA hacks. These hacks are sometimes built by people with little or no training in software engineering. This is the scariest bit of information that I have got from the SocGen scandal. Jeromé Kerviel isn't a computer genius, he knows a little VBA. Don't believe me read this.

Who would have known, an Excel bug could trigger the next stock market crash. Microsoft decides the faith of more money than they are themselves worth.

I don't know about you, but to me this looks like an accident waiting to happen. And if we don't do anything about, it will not be pretty.
