Can I somehow see the historical data for some of mine old submits? I seems to me that on https://news.social-protocols.org/ I can get the data for past 24 hours. I think that you have point with feedback loop.
We just reset the history yesterday and plan to keep data for about one month for now. In the future, it should definitely be possible to retain a much longer time span.
I just tested this with one of my news submits. I really find this to be very useful.
