You must have already heard about serendipity, the effect by which one accidentally discovers something fortunate, especially while looking for something else entirely. This is the best way to gout out of the common path instead of recycling the same ideas again and again, which often leads to the same overused solutions. But in order to find something by luck, someone should have made it available without knowing if it would be useful for anybody, and in which purpose, if not we stay in a classic system where people keep information for themselves or only give it to those they think need it. With two consequences : people we don’t know they woudl find the information useful are not informed and people we wrongly think they need it are flooded by unsolicited infomation.
This must make us remember that, when talking about information sharing, we must not have any a priori about addressees, knowing that what’s gold for someone may be mud for someone else and vice versa.
Let me explain this by the example, trough a situation I experienced myself last week.
