Why not? Suppose you are planning to go to a destination with which you are very unfamiliar. The news media suddenly fills with images of protests, stories about the collapsing economy, etc. Wouldn't you at least take some time to find out whether this is just a typical media tempest-in-a-teacup rather than something you should worry about? People don't just instantaneously know the whole story, they have to do some research to find it out. One avenue of research is talking (in person or virtually) with people who are likely to know more than you do. Until you posted the information, I had no idea that Greek tourism was up 15%.
