I'm glad you like these frameworks, and I not telling anyone not to use them. Like I said, I was just interested in hearing why I would want something like these frameworks which focus on server side templating, over a HTML/JS frontend + webservice approach. If you are just writing a webservice I think using Gorilla in addition to net/http is pretty much perfect.
shameless plug. Martini doesn't even have html template rendering out of the box. I originally built it because I wanted a better experience building webservices for Angular frontends :)
Interesting, I'll have to play with it. Thanks for sharing.
You should consider adding benchmarks to that it is easy to compare martini to net/http. This will let you keep an eye on performance as you work on it and accept pulls.
