A code base has its own style
Here is an observation, once a code base has reached a certain size, either in time or in size, it usually takes on a style and identity of its own. This is far more than just a coding style that I am talking about. I don't care where you put the braces. I am talking about the repeated patterns that you see over and over in side that code base.
An example would be Castle-inspired projects. You are far more likely to see things named SmartXYZ or IAbcAware, with the usual implications that there are there.
What are the styles that you have noticed?
