Slidin Fast, I care because the religion so profoundly affected my life. I'm curious to see where it's going and what's going to happen to it, and I think that's normal since it so profoundly affected me. My whole life revolved around JWdom for three or four decades.
Also, it still affects millions. I have family members who are in and who think something's wrong with me. In addition, it's an interesting study in psychology/sociology/etc. Some people are interested in following certain sports teams. To me, following the goings-on in JWdom is far more interesting, and it's even enlightening and educational.
