Facebook vs. Twitter

Because I am a communications student I don't have much choice when it comes to immersing myself in all that is media. With the many different vehicles of social media, I try my best to stay involved, even when I'm a terrible tweeter and a slacker of a blogger, yeah I'll admit it...
To me, there are major differences in the various forms of social media. Facebook for example is a fun and very personal way of networking. You meet new people, you add them, you look at their profile, see pictures and create a schema of this person. Bottom line: you get to know them depending on how they have presented themselves in their profile.
While with Twitter you try to find a person, add them and then what? You read their profile... yeah... and then you see little blurbs of what they like or what they're doing or what they're pondering about. But you if you start following celebrities, who even knows if that is the actual celebrity tweeting all that stuff. There's a good chance it's some PR person tweeting for them.
Now in the world of public relations, I can see how Twitter is a valuable form of media. It connects you with others for one. The most important factor, I think, is that in the case of publicity, and something happening to a celebrity or organization, the celebrity or organization involved can respond whichever way they like. Say if I had a lot of followers because I was a celebrity and the papers accused me of doing something terrible. Depending on how I responded on Twitter, Facebook and on my blog, I could either get good or bad responses which equal good or bad publicity.
So in order to stay in the game, stay involved and on top of things, you really have to take part in all vehicles of social media, not just one.
Now in the case of "good" people to have as a friend or to follow, I really don't think there is such thing. If you refer to good as a person that updates their status on a regular bases then, the majority of people you're following and facebooking are "good" people.
In a public relations perspective, "good" people to have as friends and followers would be accomplished business people, companies, organizations, etc that play a role in your career. Take the media for example, I am a communications student so I want to follow CBC to be kept updated on events, etc. that is one thing CBC and I now have in common, you follow them on Twitter and you're a fan of them on Facebook. Bingo. You're in the game, you're on their tail and they like it.
Facebook adn Twitter is a form of communication that works is so many different ways. Both are beneficial to the profession of PR because both connect business to audience, person to person, company to company, provider to consumer. These forms of social media, take us out of our little bubbles and connect us to the world around us, get involved!
