Thanks for the shout-out on my Re-Thinking Curation post. I feel that there's a ton of articles that are being overlooked because the users simply don't have enough followers / reputation.

There's also a massive diversity problem. Most of SteemIt loves crypto and talk about the SteemIt platform. These categories are likely to be disproportionately rewarded because they have larger audiences and more whales.

Conversely, a category like pregnancy would likely attract very few high SP users and a relatively small audience.

I'd be curious to see some statistics on the most commonly used tags among your "underrated posts" - I wouldn't be surprised to see crypto-related content filling much of the top end of your graph.
