Review My App - Alchitect
pedalpete: I personally think your installation demo would lead directly to a no sale. 
There are a few reasons.
In your demo video
1) The first thing you show is an error. I understand why you do this, but saying to somebody 'here's the error that comes up when you first start' isn't a great experience. 
2) I suspect that the installation looks overly complicated to anybody who is not already familiar with how to set-up a website and sql, and you even go on to show them how they can change their settings in text if they need to. If you made it so simple, why do they need that info. You also take the viewer to a command prompt, and look at their database tables. Non of this spells 'Unprecedented Ease' to me. 
3) You don't show what making an actual web-page is like. I suspect that is going to be the most important thing for most people. They can probably get through the install (though I suspect you should be able to make it an better experience), but I want to know what it looks like to build a site.Looking at your documentation on 'creating a page'
1) you say that a user entering a field in to a form must put the '_' character between words. If this is so simple, you should be doing that for the user. Don't let the user make a mistake, you're supposed to be taking care of them. 
2) 'Now for the really interesting part' you say. Put this code in the form??? wait, if you're making this so easy for me, why do I need to know code? Plus this is now code that I would need to learn, so I am going to need to learn how you think it is best to implement.Basically, similar to apsurd, I think you've gone middle of the road here. You've taken out some of the work for programmers who probably don't mind writing the code, and you haven't made it simple enough for non-coders, and you're forcing them to learn too much stuff.
