Are Inexpensive Self-published Ebooks the New Blogs?

It reminds me of 2003, the year I started blogging, and how some people were able to attract large audiences for their writing, and the mainstream media scoffed that they would ever be taken seriously. Fast-forward, many of those early bloggers are now considered "real" journalists, some because they went to work for traditional media brands, others because they attracted a significant enough audience on their own that they couldn't be ignored.
