As much as I understand Dan H's pov, there have been times where I've seen Ark pleasantly surprised by people's progress, without mentioning any names, especially considering the fact that they only have long distance access to us.
Thanks Rob, that pretty much confirms my suspicions. Some people will not learn even with regular hands-on, whereas other people can do a lot on their own. It's a fact of life that people are not equally talented in all things. So it doesn't make sense to deny information in the general belief that no one can use it. People who are sufficiently talented and motivated can do a lot with a little guidance, and they shouldn't suffer due to the flailings of the less fortunate.
If you put information out there, it will be of use to the people who are most likely to make progress anyway.
