One of the things you have to do as a self published author is marketing. I mean, obviously you have to do EVERYTHING as a self published author, that's the thing.
I've just finished creating a landing page for Getting to Know IntelliJ IDEA. It's one of those things that should be "easy" and "quick", and yet after all the work we put into the book, we never got around to it.
Fortunately, now it's a few months after our official launch, we have a lot more information to put on the landing page, like: videos, interviews, and recommendations from people who liked the book.
It's also yet another example of how "easy" and "quick" turns into a morning's-worth of work, and, more than that, self-doubt and dithering on where to place things and how to present information. It's a morning of Googling how to do things in WordPress.
There's still a lot to do, not least of all removing all the "Trisha Gee" site branding and making it into a proper standalone page. But it does the job.
