I have seen some people frown on a testing career! Simply put it, they are just naive. Although my business card says "developer", I could have been a great QA personnel. I have great respect for any individual with a passion for QA, which makes any product presentable to the customer.
If it were just for the developers.. well, let me not write anymore
Those are some reasons why testing is great, as Murugan Pal spells it out very eligantly. I bet that the list does not stop at 10... but this is a start.
