Nothing directed at the writer of this one single blog post, but who are these bloggers to be talking about innovation? They all use the same blogging platforms and write the same articles. And why have blog posts of this topic started to appear? Arrington writes something and all other blogging websites feel like they have to get a piece of the story trend pie and write a similar post, as well? I'm sorry but these are the kind of posts that make me shake my head.
