>, and you can learn anything from words an images.

A lot of info on Youtube is not available in alternative forms such as books or blogs with just words and images.

E.g. A random person uploads a video on how he repaired my particular washing machine by isolating the relay that broke. It's not in blog form because the guy is not an HTML expert or WordPress user. Instead, he simply used his smartphone to record a 10 minute video of what he did and uploaded it to Youtube.

Was I "fine" before Youtube?!? In the past with that type of situation, I would have spent $1000 on a new washing machine instead of spending $2 for a new relay part and soldering it myself. There was no equivalent resource available to show me how to DIY repair it. Trying to avoid $1000 by calling an appliance repairman wouldn't help because these days, they charge a $150 trip & diagnostic fee just to show up ... and then in the end, they say the electronics board that's fried is discontinued so they can't get the part which means the only the only remedy is to buy a new washing machine. So I would end up paying a guy $150 to tell me to pay another $1000 for a new washing machine... for a total of $1150. Youtube helps in avoiding all that. As a knowledge base for DIY learning how to repair random stuff around the house, there is no alternative to Youtube.
