Still on accents in East Africa, i say bring them on, let us celebrate our diversity, it enriches us. We cannot all be the same. My personal favorite east African accent is the one from western Uganda, esp the kiga one made famous by comedienne Ann Kansiime. I can sit all day listening to it.
Kiswahili is not the property of Tanzania. End of story.
