Portrait of a writer as self-publisher

The whole story of self-publishing in Kenya is yet to be told.
Methinks it probably dates before David Maillu, who probably remains the most famous self-published author in Kenya for his books like After 4.30, My Dear Bottle, The Flesh, No! and other such titles that titillated youthful and adult readers alike in the last two decades before his company, Maillu Publishing House, started disappearing from the publishing radar screen.
Of course, Ngumi Kibera remains the other well known self-published author because his book of short stories, The Grapevine Stories, won the Jomo Kenyatta Literature Prize in 1997. And in the fiction class, there is also myself.
But there are other writers who started off in self-publishing but have gone on to found credible publishing companies. Murori Kiunga, author of many self-help and business books easily comes to mind as does Mbugua wa Mumbi, also a motivation speaker and writer whose most famous book is probably Excuse Me, Your Dream is Calling You.
In recent years, some poets have also gone into self-publishing, the most notable of them being Caroline Nderitu who self-published her book, Love Only, about five years ago and now also engages in teaching public speaking.
In between these diverse categories of self-published authors are others who have done limited editions of various books, including biographies, sermons, family histories and other non-fiction work. Not all of them have been profitable and probably too few of them were meant to be. But they are all adding to the vibrant cultural scene that has spawned a fledgling culture of alternative writing and publishing.
Their, I believe, is a story that would make for good reading, considering that many of them are people who have had life-changing experiences that motivated them or have equally colourful personality traits.
The question is: Who will take the time to write this story and trace its growth and influence?
