I thought it was great for building custom workflows, and I don't know that anything has replaced it since. People seem to hate Lotus Mail in favor of Outlook, for some reason. I always thought Microsoft was way behind Lotus in the workflow department, but people were used to MS products. Maybe it got worse over time with IBM's mismanagement, and I haven't used it in 15 years. I recently had to cobble together a worfklow in Drupal, and it was terrible in comparison to what could easily be done in the late 90s with Notes (which did have a web front end by then).
