I've been on boards for 13 years and in that time I've definitely noticed a shift in some forums, but AH in particular. What used to be lighthearted and jocular seems now to be populated by posts that are antagonistic, bitter and adversarial.
Don't get me wrong, debate and arguement are healthy but there really does seem to be a rather nasty undertone to some of the posts. I long for the old days of After Hours where threads were jovial and not full of rather bitter rows over issues like abortion, virtue signalling, housing and that old chestnut, social welfare.
I miss the old AH.
