People sometimes think that saying something is more “usable” is a way of saying that you like using it better. And then they’ll reply that maybe they like using it some other way and you’re at a stalemate. In point of fact, usability is testable and quantifiable. There are a lot of places you can go to read about research-based usability, things that work for most people. I just got this link from Twitter today: 10 Usability Tips Based on Research Studies. For people who want a bunch more stuff like this, I highly recommend Usability.gov’s Research-Based Web Design & Usability Guidelines (pdf, 21MB ) which are not only great reading but they’re government documents, so free to repurpose and republish.
