99% of code is internal and something noone unexperienced will look at.

If you're writing code for a tutorial for newbies then yeah, it makes sense to add obvious comments. But that's really it. The author is overstating his case.

I have the exact opposite point of view. 99% of the code is written by inexperienced people and passed on to the next generation that of inexperienced developers.

Most development has been, is and will be for the foreseeable future outsourced, not in house. I don’t like that, but I have seen things.

Too much comment about is never a severe problem. At most a distraction.

You know what, I think you're right I should have been more specific.

99% of code that matters is written by experienced people in my opinion. I.e. the OS, the browser, your favourite apps, websites and programming libraries.

Would you agree with that?
