It's pretty common for business contracts to just end up stuck on mainframes or scattered across various systems from vendors like Oracle (the paper trails are often thrown away long time ago).

And let's be honest, a lot of folks in IT aren't exactly top performers and don't seem to care all that much. It's really the developers you find on forums like this who are genuinely passionate. You're not likely to bump into the people actually buying those big Oracle or IBM systems around here though :)
