What Jay-Z and Domainpolish taught me ...

I would have at one time agreed dumbing down is dumb. However, I heard once that it takes a more "intelligence design" (pun intended) to make something that is really easy to use. Then a design where people have to figure out what's going on.

Also there is always psychology when dealing with people. Take the McDonald's arches, they're yellow because it's believed the color yellow makes you hungry. Pink turns out to be a depressing color. Green and blue which you see a lot has ties to our innate senses. So I would say in response to the comments about colors, I think taking the time to think about it is important. Not only because you want to deal appeal inane user critiques but also because you're using every part of your SAAS design as utility.

That's the opposite of reinventing the wheel.
