Sinatra is good for building houses. I haven't seen anyone here say that rails is the right solution to everything. However, I have found that it is the right choice for the vast majority of web apps I've built. For most things you will want a testing framework, a model layer, dependency management, form helpers, routing and linking apis, etc, etc, etc. And if you're doing a medium to large size, consumer facing web site, you'll want an asset pipeline.
