Usually,you can tell. Having an obsession and just liking them are way different when you look at it.
Usually people that just like them don't go out of their way to see them. They usually don't have all of their songs,and don't even know of some that weren't released. They mostly one have one poster up in their rooms. Sometimes they don't have any. These fans don't like to talk about the Jonas Brothers in public for longer than 2 hours. These fans sometimes even have another band as their favorite instead of JB. And they usually think one of them is cute,and the other aren't impressive. How do I know this? These kinda kids go to my school. And this necessarily isn't a bad thing,they just don't like them as much as people with OJD do.
On the other hand,people with OJD can't get enough of these guys. We sit down making lists of why we like them,and usually make it to about 200 reasons. These fans know about everything Jonas,5-6 months before it actually is released or even happens. (Camp Rock,J.O.N.A.S.,Hannah Montana,etc.) We tend to have our walls covered and make videos to put on YouTube about how we are OJD. Some of these fans arrive at a concert hours before the Jonas Brothers get there. These fans can also get....well......rough when it comes to Jonas haters. Especially when they won't quit.
So....there's a pretty basic "analysis" of Jonas likers and lovers.
I have OJD,so the OJD thing came from personal experience.
Hope it helped you decide.
