One of the few things the internet is good for. I have learned a vast amount of things both archery and other subjects. Pretty much anything you want to know about any hobby is no farther than a few key strokes and mouse clicks away.
A lot people that meet me for the first time think I am a little know it all. That is not really the case. I just like research things and read. If something interests me, I look it up. I used to do the same with encyclopedias when I was younger.
Of course sometimes you have to take what you read with a grain of salt though.
