Both +1
I like both ideas so far… Mailchimp can be useful when you look at what people are interested to look at in more detail (clicking being the first sign of engagement), then umber of comments or further engagement with the content - which is the ultimate proof of interacting with the synthesis.
We can also compare how the ethnographic summary of stewardship compares with an Assembl summary of the same topic, or even a different conversation, like a synthesis of ER activity over the next months, in general.
Should we then agree to ask the Assembl folks to work on helping us import content already? This is the first step to move on.
