  Software ecosystems have gained a lot of attention in recent times. Industry
and developers gather around technologies and collaborate to their advancement;
when the boundaries of such an effort go beyond certain amount of projects, we
are witnessing the appearance of Free/Libre and Open Source Software (FLOSS)
ecosystems.
  In this chapter, we explore two aspects that contribute to a healthy
ecosystem, related to the attraction (and detraction) and the death of
ecosystems. To function and survive, ecosystems need to attract people, get
them on-boarded and retain them. In Section One we explore possibilities with
provocative research questions for attracting and detracting contributors (and
users): the lifeblood of FLOSS ecosystems. Then in the Section Two, we focus on
the death of systems, exploring some presumed to be dead systems and their
state in the afterlife.
