Well, daig is actually not a thing, it's a misspelling of "Digg". Digg is a website where people can share interesting news stories, pictures, and videos with each other. Think of it as a big playground where people can trade toys and snacks with each other.
But on this playground, instead of toys and snacks, people share links to news articles or cool videos they found on the internet. And just like on a playground, some people like different things than others. So when someone shares something interesting, other people can "vote" on it to say if they like it or not. It's like giving the toy or snack a thumbs up or a thumbs down.
Digg is based in Switzerland, which is a country in Europe. They have people working there who make sure the website is safe and fun for everyone to play on. So when you're on Digg, think of it as a digital playground where you can make new friends and find cool things to share with each other.
