It’s definitely an idea worth considering, but the network feature already does that—you can search for the people who’ve interacted with you the most, and now, basically, the people who help you the most are the ones who’ll show up. As you can see in the image below, the blue icon shows how many times that person has helped you water your trees, so it basically already finds the people who’ve helped you the most and who are most active.

Does this help with what you asked for?
