Love this idea. I'm not concerned with showcasing my favorite authors so much as having a list of them that I can click through and see if they've released any new books of late.

This is a great suggestion.

How would people add those authors to their profile?

I'm thinking adding an extra step in the onboarding would be too much.
But maybe we can insert a section just above "Reviews" where they can set their favorite authors.

To make this happen we'd also have to adapt the search function to include authors I'm guessing, so you can only select authors in our database.
