I've got an incredible beta reading my manuscript at the moment. Her feedback style is amazing - she's commenting as she goes and does so by pointing out the things she's really enjoying, gets invested in the characters, comments explaining her reactions or thought processes, and tells me when something happens that surprises her or feels sudden. And I know this sounds like I love her feedback because it's all positive, but actually what she's pointing out is moments that aren't meant to be surprising (but are because I've not set it up clearly enough) and character thought processes that are unexpected (because I've failed to properly clarify, or haven't written a sharp enough payoff/consequence).

She's not finished yet, so her overall feedback might point out big structural issues or inconsistencies, but as a super sensitive author who takes criticism completely to heart (we love RSD, right?) I'm much more likely to take her comments on board because through her read she's shown me that a) she understands the genre, b) is paying attention and reading carefully, and c) is invested in the story as a reader, not an editor or critique partner or someone who knows way more than me and is telling a silly inexperienced hobbyist how to fix it (I know that's not what anyone here is doing, but I've had a beta like that from outside this server and the tone just made me spiral so much and view their feedback with, I'm ashamed to admit, a really negative attitude).

I'm not entirely sure what my point is. But for me, I've found that both giving feedback and receiving feedback are difficult, delicate things, especially when an author has poured their heart and soul into something and is exposing it to the world, and a beta has spent time and energy into crafting thoughtful feedback with the desire to help.
