When Ubuntu came it was a breath of fresh air. It brought many new Linux users. However, even as an ardent Debian user, I find the latest Google Trend curve for "Ubuntu" quite a bit disturbing - http://www.google.com/trends?q=ubuntu

What is happening?! From the graph it seems the positive Ubuntu effect (which is positive for all Linux users) is not only dying off, but also decreasing. What could be the reason? Is it a general trend for Linux? Brrr... Or is something else?

What could be going on?! Any speculation is valid as such!
