>if you are running into bugs that take you 4+ hours to resolve, you simply have not been programming long enough.
Firefox had a memory leak that took years to track down and eliminate, so according to your logic Firefox does not have any employees that have been programming long enough.
Well, I was speaking generally when I wrote that. I probably should have put in the word frequently to be more specific. I did not mean to imply that one day you will reach a point where you will never battle with a bug for over 4 hours again! But in my defense, I did write run into bugs and not bug.
