Do not increment post view for same visitor
Refreshing a post page in a blog increments the views counting. I believe it would be desirable to not increment this number if Noosfero knows that the visitor is a returning visitor.
I suppose Noosfero can easily know if it is a returning visitor if it is a logged user (in the Noosfero instance I use, all users are always logged users). If the user is not logged, checking the IP could be an option (even it is not perfect, it would help to not artificially inflate the views counting).
The rationale of this issue is that I, as an author, want to have a better idea of how far my post was able to reach people.
