I think it could be fun but for some users, I'd imagine it could be quite unhealthy.
I mean if you're putting stanning someone who doesn't even know you exist before doing homework, studying, going to work, hanging out with friends, spending time with family, etc. then obviously that's unhealthy
However if you pop onto ATRL a few times a day to see what's going on in the world of pop and see what's cooking with your favs then no, I think it's healthy. It's the equivalent of watching sports - you want to see how your team is competing.
