I interned at IBM/Lotus in 2006, when I was still in college. I don't know much about its history pre-Notes, which is mostly what the article is focused on. But I liked the place, and I appreciated my time there. It had a lot of history.<p>Notes is a fascinating example of the power and danger of a large legacy customer base. Their UI predated Windows, and any change they made risked to either the look and feel or the backend data model risked alienating their already dwindling list of customers, many of whom were looking for an excuse to leave anyway. Nonetheless, those users kept them afloat for years, and still do.<p>It's easy to forget that the power of the platform is not in the email, which sucked; it handled authentication, security, and replication for a wide array of largely drag-and-drop business applications. If you're an enterprise, and what you basically need to automate your workflow is a form and a little bit of glue code, there's a lot to be said for that system; old companies that claw their way out of it find themselves now saddled to shaky, expensive bespoke web applications that don't work offline. Because of this, it was a devil to migrate off of; even IBM tried, and failed, to rewrite it, in the form of Lotus Workplace. Talk about lock-in.<p>Still, I'll miss the name.
