Social Networking Sites

Facebook 
Facebook is a social networking site that individuals use to (re)connect with friends and family.  Users create their own profiles and they can also add photos.  They can also "Like" pages about almost anything and play interactive games on Facebook created by companies such as Playfish, Zynga, and Playdom.  There are privacy settings that users can change to limit the amount of information that specific "Friends" may view.


Myspace
Myspace is a social networking site that individuals can also use to (re)connect with friends and family.  However, it is not as popular as Facebook since it is an older social networking site.  In addition, the website loads very slow in comparison to other social networking sites.  I think MySpace is primarily used by music artists to build a fan base and to upload their music for MySpace users to listen to.

Twitter
Twitter is a social networking site that individuals use to write short tweets.  Tweets are short updates that can only be up 140 characters long.  An individual's tweets can be public or private.  In addition, Twitter users can follow other Tweeters whether its friends, family, classmates, businesses, athletes, celebrities, etc.  Twitter is also a great way for food trucks to update their daily locations to their followers.

Foursquare
Foursquare is a location-based social networking site that individuals can use to check into their current locations.  They can check-in to locations by using their mobile devices such as iPhones, iPads, iPhone Touch's, Android Phones, and Blackberries.  Users earn user points and badges when they check-in to venues.  However, users do not have to check-in at real-time.  They can check-in to a location even if they are no longer there, so users may "cheat" to earn user points and badges.  Therefore, Foursquare's check-in is not a secure as Yelp's check-in.
