I dunno. It's all well and good having multiple "angles" on a given topic, but if a new user has no meaningful way of distinguishing between those angles then it's just going to be confusing and noisy for them.
Self-written mini-bios are not the answer here; the question "what makes this recommender different from the others?" is not something the recommender can answer in isolation, even if they're being maximally honest.
I'd love to hear your thoughts if you have a few minutes, my email is [email protected]. Can you tell me what you would do and how you would approach it? I'd love to chat if you have a few minutes :)
The cool thing is that those recommendations are vastly different depending on the person making them. So I do want the same topic from different angles and then I am going to change how they are viewed to make that more useful. As this scales I will be drastically changing how that is displayed on the homepage and topic pages.
For example, here is a future way to get books recommended on a topic one at a time... kinda like book dating: https://forauthors.shepherd.com/shelf-pages
