What I'd like to specifically point out is that I recently received an upvote with 0 repreputation. What was strange is that SOStack Overflow didn't notify me about it. I like to check my question/answer after an upvote or downvote, and sometimes delete or modify it if needed. This isn't so common with upvotes, but it happens often with downvotes. Personally, I'd appreciate getting a notification about it. Self-review is always important for me.
I believe that, inIn general, all feedback should carry value regardless of repsreputation.
