Author of Martini here. I think right now is a very exciting time for web development in Go.

One of the goals of Martini is to rally developers to create some more reusable web modules in the form of handlers and middleware. Martini has gotten a great response because it doesn't infringe it's api on your modules/middlewares.

I personally think that this is the way to move forward with web development in Go. Less coupling, pull in the dependencies you need, get stuff done.
