I believe " an investment in the knowledge always pays the best interest".
Power is gained by sharing knowledge,not hoarding it.Today internet has reached in every corner of the world.People believe in the information shared on the internet, that may be related to any topic one wants to know about,and if this is the case then we should make internet a better place so that one could get correct information.
The most common topic to speak about is human health, if one is suffering from any disease or disorder, the first thing they will be doing is surfing on the internet to get the information related to it (not trying to know whether correct or wrong) and then visit a doctor. Looking at this, i believe why not we can put up the correct information on internet so that people could actual get benefit of using internet. Wikipedia being the largest source of information,all the contributors should make wiki the "most correct source of information".
