Greetings boys'n girls
According to O'Reilly at the time being were all at the step of Web 2.0. which are when the web is a platform that can be use by anybody where Web 1.0 is only about our self and Web 2.0 is about our interaction with other in the net when it became our externalization of communication with other
Secondly we use our mind collectively i.e. what we see at Wikipedia when the user can contribute to make and editing an article this also indicate that one source of information only is not accepted again at the time being.
As we can see today, when contributing among other even now we can get paid and make money from it by reviewing other blog. Don't see it as how much you can get for it, see it as an appreciation of sharing the knowledge.
cheers
