One thing is for sure.. There is a high level of trust demanded for trailing a curator. I have run into issues trailing curators who have a different sensibility than myself. They have voted for things that I simply wouldn't vote for because I think that they are harmful to the platform, regardless of the likelihood of rewards.

For example, a curator who is looking to maximize his return might vote for whalebotted authors who devote the majority of their posts to "featuring" other authors. I personally think that this a practice which degrades the platform in most cases, because the most prominent and prolific of these tend to dedicate most of their efforts to bootstrapping friends and family with little regard for the quality of the content.

If I knew that somebody basically shared my own sensibilities, I'd have very little hesitation in following them.
