E-ficiency
When a website or browser doesn't make you want to throw your phone out the window. If you can find what you're looking for in under 10 seconds, it's E-ficient. If you're crying into your pizza, it's not.
I had to click through six menus just to post a tweet. This is not E-ficient.
The website took me 15 seconds to load. I'm not even mad, I'm just sad.
I tried to find my profile and it took me forever. This site is garbage.
