Yes, I noted that, Rooster, but I hope that this is not the case.
At this time of the year, some are busy with work, family, studying, duties, Christmas preparation, charity, and other activities, or they are on trip (having not always access to Internet), need holidays (including "holidays from Internet") - and technical problems, flu and other diseases can also cause lots of absences.
And yes, there are also users who are too easily bored and changing sites frequently.
Last but not least: quantity does not grant quality, and too big sites are very hard to handle properly.
Still, I am also worrying a bit.

Sadly enough, former friends have become bitter ennemies, and they insult each other, instead of agreeing to disagree and respect each other. Many are blinded by propaganda and fake and can't see the very problems clearly; others seem to have been deeply hurt and are embittered or vindictive and overly judgemental, and they refuse to see the different sides of the conflictual parties. And some have a strange sense of humour ...
And there are some who are purposefully sowing discord, spreading rumours, half-truths, fear and raising hate, and we can find them everywhere.
