Two years ago I began developing a large web application and I had to choose a language and stack. Having built applications on .NET and PHP most recently, I knew I could fall back on either and be safe. I decided to investigate RoR and .NET MVC. For whatever reason, RoR felt strange and I knew it would have a steeper learning curve initially, but probably be more efficient to develop with in the long run. On the other hand, .NET MVC felt a bit more familiar, and had many attractive qualities that "appeared" to mimic RoR. I went with .NET MVC. Now 2 years later I find myself spending my day job in .NET MVC and my side projects are all RoR. I found that .NET MVC was a great bridge from regular .NET to RoR. I am frustrated that I didn't pursue RoR harder 2 years ago, but hind sight is 20/20. I am extremely happy to be working on side projects in RoR because honestly it is more fun. Don't get me wrong, RoR isn't all roses, I'm just finding fewer weeds!
