I think I agree with what a lot of you are saying, but we need to stop debating this issue into the ground.
However; as a kit supplier, I have to say that a person learns as much or as little as they want to. Buying a kit does not mean you won't learn anything, it just means that you get all the parts at once. Yes I realize that buying and figuring out all the parts to get is a good learning experience, but it is also a costly one. There is a very minimal difference between getting a complete kit and buying a silk screened pcb then buying parts from a BOM.
In order to learn one must possess the desire to learn, kits do not make or break that.
I do wish that more people took more initiative to learn, but in the end all that matters is that we are happy with our own personal version of DIY.

I hear what you're saying... but I think that Freddy does have a good point regarding well-structured kits vs. building something that is less supported. I build a lot of guitar amps and started my DIY experience with a Hi Octane kit from Doberman/AX84. Downloaded the schematics and layouts from the web, built it, worked great, sounded good.
Problem was that once I was done... I felt like it was more an exercise in gaining the proper skills (soldering, casework, etc) than it was an exercise in understanding the electronics. I realized that I had a good little amp but had no idea how it really worked.
I didn't really start learning about how the tubes amplify, how to set up gain stages, how to do a proper layout, etc until I decided to start tweaking and sourcing my own parts. That is where I started to really learn. The challenge to me is either taking a schematic and trying to visualize and CAD up a layout, or designing the circuit myself. I'm not a very good designer yet but the amps I'm designing now are better than the ones I was designing a year ago. I've learned a hell of a lot more through this sort of process than I did through building my first amp from a kit, although admittedly that is all part of the process.
Same thing goes for recording gear - I have a stuffed GSSL board and all the parts sitting around... bought everything two years ago but I felt like I was just doing paint-by-numbers when I was stuffing the board and that took the fun out of it for me. I want to finish it someday, but I am more intrigued by projects like newyorkDave's MILA. I built one about a year ago before I really understood how to do a proper layout for something as sensitive as a tube mic pre. The unit sounds great other than the much-to-high noise floor. But even in failure I learned a hell of a lot and I'm pulling it apart now to do a complete redesign of the layout. I like the challenge of trying to figure out how everything is going to come together in (hopefully) noise-minimized manner.
I do think you are right in that DIY is really "you get out of it what you put in". I just feel like it is easier to kinda coast on a kit and not really put in as much effort... I'm sure I'll continue to buy kits in the future (btw after this rant I'm still interested in your great river kit!), I just think I'll tend to compartmentalize kit purchases to the "practicality" department - a piece of gear that I need but don't think I'll ever be interested in designing down the road.
I don't know if any of this made any sense... rant off.

PS - I also agree with Freddy regarding casework/front panels, but part of that is because I'm fortunate enough to have access to a CNC for engraving. I realize that not everyone has this luxury.
