Replying to Zootspace?

I invited this guy over to my place this past weekend to meet my parents. We we're having dinner when my mom asked about his interests. He started talking about skiing (obviously) but then he showed them zootspace. He didn't stop talking throughout the whole thing and he didn't care how rude it was to be watching this video on his phone while we were supposed to be eating dinner.

Needless to say, he will not be coming over again but now I'm curious. What's the deal with zootspace?
