I had the same urge to write something like this after reading the Invision blog the other day. I couldn't believe that the author (or someone proofreading) didn't recognize that the problem being described had nothing to do with personas but that those who created them openly admitted "we made them up". I'm all for opposing points of view but this was one of the more ignorant things I've ever read.

I don't think we realize the gravity of the internet being used as a platform to spread our ideas far and wide. It can have some really powerful and not always positive consequences when opinions can be thrown out across the world in an instant.
