I find that when you are developing an open source application, its rude to not comment your code. Its the least you can do to help any other developers willing to work on your project. I feel like its more inviting as well.

I'd suggest that you help your fellow developers more by writing code that needs fewer comments to make it understandable.

However, I agree that what you say is certainly true of APIs.
