I really would like to see some answers from the addressed people here ...
I am not a witness, and you know my point of view already to agree that a linear reward curve favors self-voting too much, indeed, but that I personally would prefer a curve which starts non-linear (against self-voting) and ends linear (against excessive rewards of single posts).
Anyway: good that you keep asking these important questions!
Amen!
what is it useful to us
@teamsteem (in his article above) and I (in my comment and here) wrote already what we think is useful ... But of course there are many different opinions.
I would like to read the point of views of top witnesses here, too!
