There are a lot of theories and opinions out there regarding whether or not a dislike button is a good thing. Some think that having a dislike button fosters negativity, and I can agree with that. Saying thanks and liking what others are saying makes this forum a positive experience. I just read an article that states, "Approval engenders solidarity and helps group identification." But what about those who have a dissenting opinion?

I have also read another article about how boring the internet has become since the early days when people anonymously trolled on forums and were really nasty to one another. "These days, life online has become friendly, well mannered, oversweet. Everyone is on his or her very best behavior—and if they’re not, they tend to be quickly iced out of the conversation."
