In January 2001 as the dot com boom burst online education site wwwrrr.com went out of business overnight, literally. Coverage tended to focus on the employees – who ultimately filed a class action lawsuit for back pay and 401k contributions.
Lost in that ugly coverage was the blunt reality for teachers and schools that the new era of on-line content had a very dark side. Teachers who were relying on wwwrrr’s materials on January 9th were left with absolutely nothing on January 10th. They had no warning.
When schools buy a textbook they own the thing. If the vendor stops offering the book the school still has the thing. With cloud-based solutions schools are buying a license to a service. If the vendor stops offering the service it evaporates. Teachers rightly want some assurance that if they integrate a useful solution into their lesson plans that they can use it for several years.
