Latter-day Commentary started on Blogger in 2007, then went to Dotster in 2010.
I switched to Wordpress.com in 2012. It is now (as of Oct 2014) hosted on BlueHost.
The permanant address is simply http://latterdaycommentary.com – no /blog needed.
Here is the old Dotster page: http://3tcm.net/latterdaycommentary.com/index.html
A backup of the blog can also be found at http://latterdaycommentary.blogspot.com
The backup is not current. It takes time to duplicate on two sites. I do it every six months.
The old WordPress.com site is at https://latterdaycommentary.wordpress.com/
It is no longer up to date. But I keep WordPress.com for some of the unique features.
