I happened upon this company, LearnDash, due to a blog entry – I do NOT know them. There are two reasons for this post, however.
1) If and/or when PSA is looking for a low cost LMS, there may be a reason to explore a WordPress plugin such as this.
2) Tin Can API appears to have the potential to be a big thing in developing cross-platform learning content. SCORM is really old and limited but it is used because there has been nothing else. I do not yet fully appreciate the advances of Tin Pan API, but it warrants attention as PSA moves forward.
