Which Linux Distributions Are Dying?

I just read Louis Gray’s post titled “On the Web, If You’re Not Growing, You’re Dying.†It gave me a chilling realization about web services. Like everything else, what goes up must come down. This must apply to Linux distributions too, right? So, what’s happening with Linux? Which distributions are growing? Like Louis Gray, I’m going to use data from Google Trends. People searching the name of Linux distributions on Google can be considered new users. After all, wouldn’t experienced Linux users already know where the websites of the big Linux distributions are?
