This blog is a descendant of past efforts.
In the summer of 2010, I joined with a handful of other passionate people who'd been commenting on Nate Silver's fivethirtyeight.com when that site ended -- Nate had moved on to bigger things. In the spring of 2011, four of us formed Logarchism, and that effort lasted until July of 2012. Soon after, I created two email lists, RationalPolitics@yahoogroups.com and Politicalogics@googlegroups.com, both of which have been enjoyed and used by a small handful of passionate commenters of a variety of political leanings.
A blog format seems to be better for encouraging discussion than the old email list format. Hence, this new forum. The drawback is that an email list allows commenters -- not just the list owner -- to create new threads. There are other, more complex forum formats that also allow that. I hope to find ways to welcome a number of ways for people to participate.
I'll have a couple of threads open here in a few days. Until then, welcome.
