First of all

First of all, the majority of people seem to think Facebook to be more popular than twitter. The main reason Mark Zuckerberg created Facebook was for people to connect with friends, current friends or friends from high school that you wish to get back in touch with. You can potentially connect with new friends through Facebook as well and meet different people from all over the country. When you message somebody on Facebook it’s unlikely that you will get an immediate response from that person unless they are currently on and get notified they have a new message. The reason users may not be a fan of Facebook or like twitter more is due to the fact that navigation and updates to Facebook or rather difficult and you invest more time into it.
Twitter’s popularity comes from how easily you can interact with people and you receive rapid response. Twitter’s similarities with texting are popular with the young crowd such as myself and other students all over the world. Unlike Facebooks large user base that attracts people, unfortunately twitter can’t compete with that, they are known for a much smaller user base. When sending tweets you are limited to only 140 characters, so you must be to the point when sending a tweet.
These two social networks differences there are also several similarities. You can download both of the networks mobile app to your smart phone and access the network from your phone. Tweets and statuses are similar in the sense users can see what you posted on the news feed, and the popularity and growth of both networks are the biggest similarity the two have in common. Facebook and twitter both allow you to upload pictures on your profile for people and friends to view.
