I understand the reason to camel case variable names, but I've always wondered why you would camel case a method name? why is it toString() and not ToString()? What purpose does it serve?

Methods should be verbs in lowerCamelCase or a multi-word name that begins with a verb in lowercase; that is, with the first letter lowercase and the first letters of subsequent words in uppercase. Local variables, instance variables, and class variables are also written in lowerCamelCase .
The name refers to the internal capital letters, which resemble the humps on a camel's back. For example, ComputerHope, FedEx, and WordPerfect are all examples of CamelCase.
Camel case starts each new word in a complex variable name with an uppercase letter. You can capitalize the first word as well or leave it lowercase. When the first letter of the variable starts with an uppercase letter, it is known as upper camel case.
/ˈkæm. əl ˌkeɪs/ the use of a capital letter to begin the second word in a compound name or phrase, when it is not separated from the first word by a space: Examples of camel case include "iPod" and "GaGa".
A lot of conventions say you capitalize the first letter of types (classes, structs, enums, etc.), and use lowercase otherwise (functions, members, etc.).
If you follow that convention, you can then tell just by looking that MyStruct.MyType refers to a nested type, and MyStruct.myData refers to some form of data, and MyStruct.myFunc() refers to a function call.

It's just a convention. Like all conventions they only serve to, in the minds of their creators, make code easier to read and maintain.
