For most of the WT history someone on the GB had a very active roll in producing content. Russel, Rutherford, Fred Franz, Ray Franz were all prolific writers of propaganda content.
I am not aware of any GB members today who are as actively involved in producing content and a primary reason for the recycled food and dumb down content IMO.
For this reason I say they are dumber then previous members.
For what they lack in writing ability and producing new spiritual content, they more than make up for in shrewedness.
Totally agree GB1 had some respectability, as in Grandfatherly. The new bunch are like used car salesmen. Anyhow now that TTATT is out it's a done deal their glory years are over thanks to the abundant information that's out there on WT history.
