Free information is a teaser and introduction, people will not pay what you are trying to sell unless they try it and feel it might be worth. Am i right?a person's expertise and knowledge is not supposed to be free, because he makes effort on learning and even pay for the courses and books,he teaches people to shorten their time that they have to spend on self studying, since time is money, why not get paid by teaching others.
Yes, i do use web2.2 to create content and share with people, some are free, some are not, including my class on wiziq, my presentation,ebooks,videos. Many good teachers on youtube, they do it for free and give themselves a chance to show case their knowledge, so people will be directed to teacher's website, then they will go through a process from visitors to customers, eventually the teacher get paid but it provided the teacher's website has something to sell.
I find valuable information from many different ways, but first thing first is I must know how i want to do, then I start taking action, when i have problem, i search answer from google and find some website provide valuable information,usually it is blog, then i subscribe to the RSS feed so that i can continue learning from that website. Usually i can find the answer through google by myself , otherwise I will try to raise my questions on social media or forum or to my friends.
Good topic and questions Marian!
