Learning New Skills: Does anyone even still use RPG Maker?

I'm looking for a skill that I can learn and apply online. The last skill I chose was the Japanese language and I spent 2 years learning it. I'm now at the point where I'm looking for something else to do.

I was thinking of learning Ruby on Rails and using it to make a game in RPG Maker. Maybe sell it on Steam. Maybe make five bucks.

Does anyone have any better suggestions?
