Hey Jimmy why do you always address your posts to Lisa? Don't you want input from the rest of us? LOL Just kidding with ya!
I personally don't think you should start with an ebook. Ebooks aren't necessarily going to help you get a good ranking in Google. Yes Google can read PDF files if you create it Adobe Acrobat but you need a nice, clean HTML, search engine friendly site to start getting traffic.
I'm tellin you man... take the time to focus on your site and get that traffic. Once you have traffic, making money is the easy part. The challenge is bringing the traffic in, but it will be worth it. Ebooks, forums, and all that additional stuff should come later. Learning how to optimize a site for traffic is the first step and that's why it's so important you define your target audience.
First step... You're a developer right? So who do you want to target? People who want to learn ColdFusion for example or existing Webmasters who already know the various languages but want to take it a step further. It's really important you begin by focusing on that... otherwise it will be hard to know WHO your audience is. The better you know your audience the easier it will be to refer them to products and earn a commission.
It sounds so trivial but it really is worth taking the time to write down who you want to visit your site because if you clearly know who you are targeting, it will help ensure your content meets their needs. Don't think about what YOU want on your site, think about who your future audience will want to learn.
Keep in mind if you buy Site Build It! you won't be able to do a lot of the programming that you do with a regular host. Currently there's no MYSQL support and a lot of the other technical features other hosts allow. That's because Ken Evoy wants you to focus on building your content and getting traffic.
You can still upload your pages through Dreamweaver, Homesite or just hard code your HTML in Notepad if you wish, but instead of using a standard FTP program you'll have to use SBI's ftp tools which are all built into the SBI "system" that is all browser based. It's a lot different and quite a change for developers because they are so used to being able to control every aspect of your site.
I don't think it's a bad thing because I own SBI but I'm just letting you know. It is really going to teach you to focus on researching your niche and learning how to write/market. After all that's what gets you paid. If nothing else it will teach you how to get a top rank in the search engines.
But as someone else said be prepared to READ. If you don't like to read and are not patient don't buy it. You can't be in a rush or you'll waste your money.
