this is a very important question!
This is a nicety; while appreciated it looks like you are trying to suck up to Nancy.
(taking into account what Lumifier said about the app) in your description;
We also intend to run randomized control studies on our content's impact, as described in our theory of change. We have written up proposals for those studies, and are currently trying to get funding for these studies.
Is the only thing you said are doing to be checking on what you're actually teaching. And it's something that has not happened yet. (granted these things take time). I read the entire post as; "nothing yet, but we want to - in these ways...".
randomized control studies on our content's impact
depending on the method (if done with web content) could be described as A/B split testing. Which is standard these days for internet behaviour of groups spreading clickbait, not an accountable test.
I would suggest not taking Lumifer's description of his initial impression of the sign-up page as indicative of the app itself. I think there's sufficient evidence of Lumifer being not unbiased in describing Intentional Insights content. So consider checking out the app itself.
Here are the study proposals themselves, which you can evaluate yourself for whether they are A/B split testing: 1, 2.
EDIT Forgot to mention, my comment on the nature of NancyLebovitz's question had to do with my own desire to signal that this is a very important question to me, not ...
Richard Kennaway has posted about an edit war on the wiki. Richard, thank you.
Unfortunately, I've only used the wiki a little, and don't have a feeling for why the edit history for an article is inaccessible. Is the wiki broken or has someone found a way to hack it? Let it be known that hacking the wiki is something I'll ban for.
VoiceofRa, I'd like to know why you deleted Gleb's article. Presumably you have some reason for why you think it was unsatisfactory.
I'm also notifying tech in the hope of finding out what happened to the edit history.
