Simple go library to interact with Gravatar.
$ go get github.com/automattic/go-gravatarIf you already have the hash, build a new Gravatar object and generate its url like so:
g := NewGravatar()
g.Hash = "hash-goes-here"
url := g.GetURL()
If you have an email address:
g := NewGravatarFromEmail("foo@example.com")
url := g.GetURL()
