Positively and negatively.
Through internet I learnt that there is still good (and affordable) hunting in Africa. And you can not learn this through national geographic or animal planet documentaries.
Negatively: internet has given the (good) tool for anti hunting various campaigns.
Often, they are fueled by hunting photos served by hunters them selves.
Presently, there is more benefits from internet to hunting (by sharing knowledge, experiences, information, etc) then drawbacks, but I see this gap reducing at fast pace. Pictures of dead animals are affecting (laymen) public opinion, legislation, international regulations, etc...
