Social Media is changeing, but just like anything it has its ups and downs.  I would say it is useful for example right now im useing social media for school work and busness, and I think thats all it should be used for.  The down side people tend to get lazy and abuse this social media for things that are not important.  As a teacher it is very useful for student and teachers for work or information about assigments. I found this website, it look interesting for my group project, I will see if I can find other sites.
