Freedom of Speech?
Sooo don't call me a suck up or anything but, I chose a particular quote from Dr. Jerz in this article on the importance of filtering your thoughts.
"I remind students that their blogs are public," he said. "Someday, they'll be in a job applicant pool, and a potential employer will run their name through Google, and the angry ranting Web log they wrote at age 17 will turn up."
I know that anger and negative comments spread by word of mouth which is bad and they're even worse when they are documented on a blog for the entire world wide web to see. A blog can be your own personal rant page but there are consequences. Even if you're ranting about a computer-illiterate student or professor, these guys may have friends who aren't. It only takes a click of a button to ruin a reputation nowadays.
So maybe you don't get caught posting rumors and negative opinions about that person.....YET.
At least 4 years down the road, a curious employer may google your name looking for a reason NOT to hire you. He or she finds some disturbing, yet long-forgotten blog entries from the college years. Aren't you learning to be professional in college? Clearly it hasn't worked and there goes your 6 salary career out the window all because you couldn't keep your ill-mannered thoughts to yourself.
On Richelle's comment, she referred to the similar "you-should-know-better-because-you're-learning-professionalism" ordeal. In her words, don't leave negative opinions and "they won't come back to haunt you."
Personally, I'm not a negative person, however when I have my days, I certainly am not going to post something on my blog that I wouldn't want the world to see. Plus my mommy raised me right, If I don't have anything nice to say, I don't say it at all.
