So, this is kind of unrelated, but am I the only one who prefers text to videos/audio? I know I can scan through text a lot faster then sitting and listening to someone talk
Free is a tactic used a lot for tech companies. This is because people have to be shown why this new technology that you created has value. If it wasn't free then it is like you telling someone i have this cool website that can make you more productive, give me $20 to find out if it works for you. Most people won't pay for that because they are happy with what they are currently doing.<p>Look at skype. If skype was not free no one would care to try it because the available options are just as good.
