@b0rk in the same vein: it's taken me 40 years to learn basic surgical procedures (removing splinters from my skin), I just don't get that much practice - or have that much interest...

People have different areas of expertise and interest. I am extremely unlikely to ever use the "basic readline commands" in either a professional or personal capacity as I'm not a programmer.

So, yeah, the "I can't believe it took so long comments" are ridiculous.
