You can use a dispatcher library like httprouter to get slightly more convenient URL routing and parameter capture. There are a whole bunch of "middleware" libraries that intercept requests and provide sessions, CSRF protection, &c --- and no one "framework" provides all of them.
But keep net/http visible in your code. It'll maximize compatibility with other libraries, keep you from having to write bizarre shims, and ensure your code is idiomatic.
When someone writes a library that coherently unifies persistence and request handling and view rendering, it'll be time to consider frameworks. But current Golang frameworks aren't ambitious enough to be worth the headache of, in effect, coding to an idiosyncratic alternate universe of request handling.
