First we were all Jehovah's witnesses. That was the most important thing in our lives, our raison d'etre. It was how we identified ourselves. Most of us felt a compulsion to make others aware that we were witnesses. Then, usually after a period of disillusionment, we became ex-Jehovah's witnesses, and that then became our raison d'etre. Now we had to tell everyone just how awful it is being a Jehovah's witness.
In a way, we actually become witnesses in reverse, we actively discuss "This bad news of the dubdom" as avidly as we once did when promoting JW beliefs. We post eagerly on sites such as this and contact with other ex's becomes more of a delight than any dub assembly could ever be.
Eventually, though, for most of us anyway, this phase also begings to fade. In time many of us don't even want to think about our lives when we were in the JW religion, we just want to leave it behind us. A few are able to use their experience to help other departee's pretty well on an ongoing basis. Forunately, rare pro-active persons such as Alan F, Randy and Norm seem to have developed the ability to lead a productive life away from JW's and are yet still able to occasionally wear their dub hat to help newbie ex's.
So the fact that most of the less pro-active posters eventually cease to post here shouldn't, IMHO, be a cause for sorrow, even if we do miss them.
Really, when a person posts here, often prodigiously, and then just disappears, it's a sign that that person has actually realised his goal and become totally reintegrated into normal society.
Which means that this site has helped with an excellent job of work!
