I have been watching this thread and finally have a moment to throw in my 2 cents.
First things first, I really appreciate the sharing of technique. I know that one of the main reasons people use RapidWeaver is so that they are not required to code. This is exactly why I started using it. However, now that I am a developer as well as a designer I greatly value more technical conversations.
That being said, I think it is important to note that this solution will not be practical for the majority of users. Developers like @joeworkman have spent a tremendous about of time providing amazing solutions which are far simpler to use in a RW environment and require zero database setup.
Something like mySQL may seem simple enough to some of us, but lets also remember that for many users they haven't even heard of FTP until they open RW for the first time.
I would also caution fragmenting your system architecture by splitting between RW and Wordpress. I know some people use WP specifically for managing a blog that is imported into RW. Although this is "free" and open source solution, if you are self hosting, you will then have to worry about all the maintenance that comes along with using WP.
Yes, WP is used on over 25% of websites in the public DNS. However, this doesn't say how many sites have actually been completed, are receiving traffic, or still functional. One automatic update and any of your themes and/or plugins can break your site. Also, not updating your WP version, themes, and plugins is never a good idea with WP.
WP is the perfect platform to use if you wish to be an easy target for hackers. I use a Linux distro called Kali and it comes with a dozen or so tools for penetration testing WP sites. One the tools is called wpScan. All I have to do is put in a URL of a WP site and it will show me all of the vulnerabilities for that WP version, themes, and plugins. It then provides a convenient link to where I can learn all about the vulnerability and how it can be exploited. All of this has provided many businesses with the opportunity to make a ridiculous amount of money maintaining, troubleshooting, an recovering WP sites.
Lastly, before I move on for a bit, WP can only be "free" because they have highly inflated pricing for their hosted plans. It is not fair to compare this business model to that of Realmac/RapidWeave. Realmac does not have a subscription service that is priced any where as high as WP nor do they have as large of audience. Maybe this will change in the future.
In conclusion, I think conversations about code should be highly encouraged within the community. Along with that we should remember that code is not for everyone. Perhaps we could have a Code Junkie category added to this forum. Also, if anyone is using WP or plans to use WP they should also plan to invest the time to learn how to secure and maintain a WP site.
