Net::Posterous::Tag - represent a tag in Net::Posterous
This is one of those weird bits of Posterous where they represent the same thing in different ways.
In this case there are 3 different ways of representing tags. The other two forms are abstracted away and this form only gets used when getting global tabs with
Get or set the id of this tag.
Get or set the value of this tag.
Get or set the number of posts that have this tag.
