OpensourceCMS has a short interview with Matt Mullenweg on there site. Unfortunately, with no date next to it, I don’t know how old or how fresh this interview is. They go over a few things, and really it is nothing substantial or new though Matt does have one interesting and quotable sentence in the interview, “I think it takes 10 years to make truly great software. (We’re only 4 years into it.)”
