Even worse, what if those people aren't even with your company. I've had a lot of occasions where I've had to go through code bases written be someone else, without documentation who are no longer around. Its slow work, and requires quite a lot of code reading. Their are some fun aspects to it though. You get to look at various different styles of programming. Some people seem to go a mile to make a simple thing extremely complex. Others write code that documents itself!

You can learn a lot from reading code. I believe in Simple Code, thats easy to read and understand. Maintaining code is hard.

I used to be this way. I used to love complicated designs and read everything I could about complicated technologies.
