Social networking sites and knowledge

Internet is so popular that everyone in today’s world likes to use internet to search something. With it people can get knowledge almost about anything. They can connect with other people and share their knowledge through internet. Wikipedia, YouTube and Facebook etc., social networking sites are the examples. These social networking sites are also creating problems and limiting the chances to get true knowledge. On the site like Wikipedia, where anyone can upload or change the information, is making hard for us to get the real story. People who are sharing their knowledge on Wikipedia aren’t the experts. Some of them put information just for the fun without caring that it can harm others. Internet is a very useful invention, it made our life very easy but some social networking sites (for example: given above) are also making our life hard.
