There are MANY reasons I love this app, here's just a few.
1. Knowing server locality is useful, and can provide evidence of phishing/spear phishing websites misrepresenting themselves/their location. 2. Save money by tracking down a site, such as a "Canadian Pharmacy" to find it's really in China, and there is a high probability of counterfeiting there. 3. sometimes, it's just fun to have and play around with.
