From 2006 until mid-2015, my blog was located at ed421.com. In mid-2015, for a variety of reasons, I chose to close that blog. I did download the entire collection of posts, but am still in the process of uploading that database to this blog as a true searchable archive.
In the meantime, you can see the older versions of that blog and the archived blog posts using the Wayback Machine:
Please note that the ed421.com URL is now owned by someone else and the blog posts that currently exist on that URL are not associated with me.
LEADERTALK
LeaderTalk was a group blog hosted by Education Week Magazine, and I was one of the bloggers. The blog stopped publishing several years ago, but EdWeek has continued to maintain the archives which you can find here.
