At the risk of adding to a thread that may have run its course, I'll chime in.
My community has a built-in measurement tool for things like the amount and types of content, the number of users and their activity.
And we also have an add-on called "Resonata," that is supposed to measure "sentiment." Honestly, I find the tool so opaque (not only does the UI stink, I don't have visibility to what determines the sentiment is positive or negative), that I don't feel I should trust the tool. But I'd LIKE to know the sentiment of specific content.
I would really love to know specifically what a particular user does in a given month, what they look at, like/dislike, share, vote in...I'd like to know this info by member type, location, which of my company's products they use.
I "could" find out all this if I knew how to use the API that my platform has available. I'm not a dev, I don't know how, and even if I did, I could literally spend all my time looking up that stuff and not administering my community. So, you have an amazing opportunity offered to you! I hope you get good stuff!
