This is a response from another thread:
This being a wiki site... one that is to bridge all peoples, international boundaries, generations, and cultures... we must allow for others to express themselves freely. It is the standard in internet culture now. In order to stay successful and continue to become more popular it is important to give people the ability to communicate and not to censor or restrict any more than necessary.
There are a variety of different people using this site for different reasons. We have to be flexible to accommodate everyone.
Some people feel "this is my XXXXth great grandfather" doesn't belong in the public comment board on a profile. Those people have the ability at WikiTree not to post such a thing.
Some people feel that it is entirely appropriate and are inspired to do so. At WikiTree (and other popular wiki sites) they can.
When WikiTree was created (by a proven wiki-genius) the vision was to use the public comment boards on the profiles for all types of communication relating to the profile and genealogy. The comments in debate are well within this description and intention.
I believe we agree that the comments are ok on our personal profiles. Probably even on our parents "this is my dad" is fine. I don't think either of us finds it productive on 11th generation ancestors and likely are not inspired to post them. I think our personal opinions are in agreement on the use of them. I mentioned in my original post that age of the profile was to be considered.
If we disagree about anything it would only be level of control and censorship.
I think the thing to discuss would be how to encourage use of the comment boards in relation to the ages of the profiles. Instead of treating them all as open for anything or all of them as restricted, maybe dates would be considered.
Maybe something along the lines of encouraging posting on newer ancestors while guiding people towards more productive postings on ancient ancestors.
Doing a positive thing like educating people or promoting a view is far more wiki than laying down the law.
