To these three questions:
On March 15th, AARP announced the Politics and Current Events was closing on April 5th citing the obvious that the nation is divided. Was this an admission that AARP is incapable of moderating ' robust ' discussion? Not so sure that this was an admission of that, but it's possible.
Was closing the forum the result of looking into the complaints illustrated by the two-letter writers as AARP committed they would do? That is also a possibility, I will explain why after responding to all three questions.
Should the two letter-writers anticipate a personal response from AARP as committed? I would say that's it's natural to expect a response but after this long my expectations would change.
It is possible that AARP did indeed investigate as a response to the letters? Perhaps they did and decided that closing the forum was a better or easier way to address the problems within the forum. Perhaps contractual language prevented them from interfering with how the forum was being moderated. Perhaps closing the forum ended that contract and now leaves AARP free to contract others to moderate and manage a new political discussion forum. It's hard to believe that AARP is not capable of having and managing a political discussion forum, perhaps closing this one was the best way for them to have a better forum in the near future., it is my hopes that they indeed do. If so, I hope that those who post there will take heed and be more respectful in the way that they address others within the forum, and research what they read in an article to determine that it is indeed factual before they post it. Yep, many questions unanswered, only time will tell.
