We all make assumptions, it’s natural and normal. But we also need to be jolted out of those assumptions on a regular basis to help us see that not everyone uses the web the way we do. I’ve talked about loving doing support for that reason, but I also love it when I’m on a slow network, it shows me how some people experience the web all the time; that’s good for me.
I’m privileged to have fast devices and fast, broadband internet, along with a lot of other privileges. Not remembering that privilege while I work and assuming that everyone is like me is, quite possibly, one of the biggest mistakes I can make.
