From experience you don't tend to see tags very often other than when decoding/encoding JSON. If you use an ORM maybe you use tags as well.

Other than that, their usage (at least to me after working with Go for a year now) is limited to things like Toml/YAML decoding for configuration, or (shameless plug) configuration with https://github.com/vrischmann/envconfig.
