I personally expect professionalism from government websites. And when buying products and services from private companies, a professional looking (and well working) website is something I want to see. Makes it more credible for me.

If the technical parts company I’m contacting has a poorly functioning website with anime shit in it, I’m definitely not going to run that by my boss lol. Sometimes the cartoon things can be used to distinguish yourself from the competition of course but I wouldn’t gamble on that in my field.

There’s a time and place for everything.
