Yes, attrackting tourists from outside the country is a good thing, but the main idea would be to have the locals take up the initiative, because not many foreign people will place caches here.
A couple of days ago I placed a cache near my home (it is not yet listed on the site because we want to be sure, that the location is good), and I put the indication in english, romanian, and hungarian too, because there are lots of hungarians here.
