The death of variety?

Have you noticed this trend? You had a great idea for the next blog post and decided to write about it, only to stumble upon the same one while surfing your friend’s blog right before you click on post.  Is it possible that when human read the same articles, they will eventually come up with the same inspiration? Granted there’s always the exception, but in general?

I am considering this possibility after reading researches done on brainstorming sessions. Varied ideas are 50% less likely compared with a virtual group where people are separated from each other.

My own experiments concluded the same thing. Brainstorm sessions are actually better at bringing people to the same conclusion than facilitating new ideas. Is the conclusion then, to become a hermit and ponder the questions by yourself?
