I've played Zynga Poker a few times but I never really got into it as some of my friends. I have some friends that literally play their poker every day for hours and hours. You can't separate them from their phone!
For me, poker isn't that interesting because I can admit that I don't really know too much about it. Just the very basic rules but that's it. I think that if you want to properly enjoy it, you have to learn a lot. Poker is not an easy game and takes a lot more concentration and effort than most people imagine. Especially if you want to earn real money. It's easy to lose.
