Scientist vs science fan (HEY GUESS WHAT THIS ISN'T A LINK!!!!)

Hi guys! I was just thinking about the difference between being a scientist and a science fan. I'm a senior in high school, and I realized that while my grades in AP science classes are just ok (B range, usually,) I love reading about the sort of thing posted here. Sometimes after I share a fun fact I read somewhere, I feel like I should ammend it with, "but I'm not actually that good at science. I just read this stuff". Does anyone else feel this way? How many of you are actualy proffesional scientists, and how many are fans? Do you fans ever feel like a poser?
