Rodders, I'm with you on that impression; but, having been a member of such clubs (both book and film) before, this tends to be the usual run of things: initial enthusiasm, mild but interesting input, and a gradual fading of interest until something is picked but no comment whatsoever is forthcoming. It is, I fear, a sign of the times that people really can't retain an interest in anything like this for very long, but simply drift off into other areas.
As said before, though, I'll be more than happy to be proven wrong....
