Lauryn was immensely talented, made excellent music and had tons of charisma performing on stage, but she just didn't have a star personality. Meaning she didn't crave the spotlight, she didn't eat up attention, she didn't play to the camera's, she didn't like answering questions about herself. Most of the time, people like that don't last longer than a few years. Celebrity overwhelms them to the point where they become paranoid, bitter and reclusive. They'll end up running away from fame and that's what she did. Lauryn didn't have the mental state to keep her star back then and 15 years later I doubt much has changed. We'll just have to treat the Fugees and her solo material as wonderful time capsules of their day.
