Depends. If what you need to build is actually a simple interface between database and front-end over an XML or JSON API, Go's not that much heavier than the alternatives, with the promise of more performance in the future and with less code than many other libraries require. Plus if you host on Google App Engine, it's free to start. Even the HTML templating has built-in context-aware output filtering for XSS prevention.
That said, Rails, or any language developers are more familiar with, can be faster. At that point, I'd argue even static HTML pages might be one of the fastest MVPs to put together...
