Personal user accounts: If a site allows visitors to create their own accounts that they can log into, then that's a good first sign it might be used for some kind of user-based interaction — perhaps social interaction. Although it's possible to share information or interact with others online anonymously, having to create some kind of user account first is more of a common, standard thing.
But the money making potential doesn’t stop there. There are now sites that work in conjunction with Facebook to help you make money. The “My Merch Store” app through Zazzle is one of those sites. Zazzle will allow you to create and design any product on their site, free of charge. Then, you can pop on to your Facebook and sell it. This will work for anyone who has a design background or who may want to sell products made by other artists, or you can try out Cafe Press and sell things through their online store.
Observers have noted a range of positive and negative impacts of social media use. Social media can help to improve an individual's sense of connectedness with real or online communities, and can be an effective communication (or marketing) tool for corporations, entrepreneurs, nonprofit organizations, advocacy groups, political parties, and governments. At the same time, concerns have been raised about possible links between heavy social media use and depression, and even the issues of cyberbullying, online harassment and "trolling". Currently, about half of young adults have been cyberbullied, and of those, 20% said that they have been cyberbullied regularly. Another survey in the U.S. applied the Precaution Process Adoption Model to cyberbullying on Facebook among 7th grade students. According to this study, 69% of 7th grade students claim to have experienced cyberbullying, and they also said that it was worse than face-to-face bullying. Both the bully and the victim are negatively affected, and the intensity, duration, and frequency of bullying are the three aspects that increase the negative effects on both of them.
