The question has been asked once or twice. Maybe a bit more than that.
But the answer is not available. Sure there are tons of rants and flames and trolls answering but they mean very little when it comes to wondering what to use and how it works. Facebook? or Twitter?
How does Facebook work? how does Twitter work?
To begin, you must have one friend on either network, or they both get very boring very fast.
Then again, you can always make new friends, but you have to be willing to go out of the normal operation of either network.
Facebook
Facebook is a quiet little place where you can see updates of your friend’s current events. If your friend posts them to their Facebook account. Many people have a program on their cell phone, called an “app”. This app allows them to post to their Facebook account while they are out and about in public. This allows them to say stuff like ” at Raging meatball concert and saw a man stage dive on to a crowd of women”. This let’s all of their friends know, that they are at a raging meatball concert and they saw someone stage dive (jump from stage high into and on top of a crowd) landing on women. With Facebook you can type very long messages for your friends to read and add videos directly to your page so your friends can watch them. In most cases that is true. Except with the Facebook application on your phone, you can only type 140 characters. Most people use the Facebook app. On Facebook you can search your old school, or your old job and find people who like that place, now you may or may not have similar interests beyond that , but hey you can always try by adding them as a friend. Beyond that, you kind of have to already know the person before they become your friend. You also get bombarded with requests to join people in a game they play online. And there are millions of games on Facebook. So the requests come constant. all you can do is ignore each game as it it sent. Eventually you will block every game that everyone of your friends play.
You can upload many photos and many videos to Facebook.
With twitter, you have a very fast past messaging system if you have enough friends or as they are called on Twitter, “followers”. Really you can follow anyone and watch their activity stream. On twitter you have the chance to block someone specific from seeing your Twitter stream or Twitter posts at any time. not many people bother with that. Hard part is adding people to follow, and even harder is adding people to follow you. That is of course if you use the Twitter system for adding friends. There are however, a few websites that let you find people under specific interests Like WeFollow. This allows you to program the information you see on your twitter page, and have it defined by interests or locations.You can upload photos and videos to other systems that work with Twitter.
You can add news channels on Twitter and get news updates before anyone. you can add your favorite musician on twitter and find out what the heck she/he is thinking before they go on stage.
Downside is there are a bunch of spammer on twitter, so be ready to get nailed with crummy laptop deals. So choose the people you follow, carefully.
Truth is. It looks to me that twitter is more popular and more actively social.
