Updates to LessonIndex.com
I’m currently uploading new versions of nearly all pages at LessonIndex.com. This is the first major update since February.
I’ve added many links to new resources, and I’ve also removed several hundred “stale links” to resources that have simply disappeared (mostly lesson plans which have vanished from school and college web sites).
The most visible change: I removed the Amazon “skyscraper banner ad,” which visitors rarely clicked.
