Ruby falling out of fashion?

Ruby is falling again on the TIOBE index.

It’s not a cause for alarm, but I will continue to look at alternatives to Ruby for the long term. Microsoft’s .NET is still something I would like to come back to and there are more opportunities for it as well.

While not directly related, I also did notice that Thoughtbot have made their learning platform, Upcase, free for all. An attempt to get more developers to use Ruby?
