Social Networking can be good:

When everybody thinks of social networking, they typically think of facebook and a way of connecting to friends. Social networking is that but it is also so much more. Social networking can give one access to different tools for social aspects as well as work. Social networking can allow businesses to spread the word about their product/business, and can also allow their business/product to grow. Social networks allow you to get yourself out there in the global age.
Below are some sites that are fact based about social networking:

When using social networking sites use them in an effective use. Make it simple, don’t slug through information you do not need nor do you want to read. Use the privacy and account settings to minimize your site to your needs.
