I do go to wikipedia and google, i am guilty about that but you can find some good information even though it is not a primary source, but that is the rsick you take when researching for information. I also go to youtube to find informational videos on HOW TO do things and it is a great tool to use because in strength and conditioning you have to do hands on and visiual learning to execute what you learn. i dont have any authors i follow but i do like to look at MLS soccer clubs webistes for strength and conditioning. from the teams coaches and to better advance my knowledge, what bwetter way to learn somthing than a person working with professional athletes , I would say youtube can get distracting because you look for informational videos but can get sidetracked from somthing that isnt really related to what you are looking for and next thing u know it you are watching a video about someone dancing or singing haha.
Technology is a good way to learn and in this day and age everything is evolving so i beleive everyone should jump on board in this new way of learniing because i beleive this is the direction everyone is going.
