They are simply not hardcore!... They don't know ANYTHING about Bible prophecy, doctrine, etc
In my area that's true about all JWs - not just the 30ish. The "hardcore" days of deeper, meatier publications, doctrinal debates, deep research, etc. are over. JWdom is more softcore and social now. JWs are popping out babies all over the place, but when I came along, there was strong suggestion that it wasn't the time to have children because the end was imminent.
I'm keeping my bound volumes for the same reason. However, I sure wish I could find a CD with scans or a place to download scans. I know the Watchtower Library CD had the mags, but it doesn't have the photos, illustrations, charts, etc. All those bound volumes sure do take up a lot of space.
