No more Ad breaks - thanks Pi-hole

While browsing through Raspberry Pi’s sub in Reddit, I came across Pi-hole. Pi-hole is an interesting project, claims to be black hole of Ads. I guess the pi in the name refers to Raspberry Pi. As my Pi3 was lying in the corner unused, I went for the Pi-hole installation. Before continuing further on the experience, we need to discuss why the ads are bothering? What’s wrong with ads? I agree the ads are the revenue source of websites.
