Most of the examples posted from this website are a little basic and don't take you much further than the pkg docs here. Also, there are problems with the menus on chrome, advanced programs menu contains nothing. I do think this website needs work - go by example is a better example of a website of sample code for small tasks in go.
This is a little short. It'd be nice if it had some more detail on the different options for logging and the tradeoffs involved. For example for some apps you want to log to a file so you have something to inspect, for distributed apps you probably want to centralise your logging somewhere - log to stdout and have the logs shipped somewhere else, or send them from the app to another server. This just goes over the basic usage of the log pkg, which is pretty straightforward anyway.
