"Are you in the software business? I bet most of you would answer no. So let me put it another way: Do you have a website? If the answer is yes, you're in the software business. A website is software. It has utility, and that utility is accessed via an interface on a computer or mobile device. That's software."
Most business with a website are no more in the software business than they are in the electricity business or the plumbing business or the furniture business, even though without these things they would not be able to operate. Using software tools does not mean you are a software engineer/developer any more than flipping on a light switch or changing a bulb makes you an electrician.
