Your mainly positive remark about the series is taken as a compliment. Yes, activity has really slowed down on TN and it seems to me that Facebook may be haven to those who want to be more defensively selective amongst the community. Some have intimated to that effect. However, Facebook does nothing for me but that is a matter of preference. Other than that I am not aware of the expected reason for the decline and I hope it will pick up again to its former extent.
