I just discovered (thanks to a reader who pointed it out to me) that the Heraclitean River blog no longer exists. I don't know exactly when it went down, but it's currently occupied by a domain squatter. According to the Wayback Machine, the site seems to have been down in March 2018 (the last capture) and the last valid capture of the home page was in October 2017. So we can assume that it went down some time between those two dates.
I don't know why the site went away, but as a part of my discovering this, I read the last article posted and since it is very interesting, I'm sharing it with you. Please read the full article and share it with your friends - it's a fascinating read.
