Ruby goes up for 11 postion and get the highest growth rate (+2.31%) among other programming languages. I beleive there is lot of potential of Ruby. According to TIOBE,

Both languages are boosted by their corresponding frameworks, Ruby On Rails and Ajax. This might be a new trend. In the recent past it was necessary to have a large company behind the language to get it in the spotlight (Sun with Java, Microsoft with C#), but nowadays a killer app appears to be sufficient. Viral marketing via the Internet works!
