I added a link to "Programmer Competency Matrix" a few days ago and have thought a bit about it :

Well all these skills are very fine, and you should strive to get them.

BUT don't forget that people do not want good looking and well crafted software.

People want something to help them solve their problem.
Look at twitter - a very successful service - but not very well crafted...
So to be a good developer you need to understand peoples need, and put that above your urge to create beautiful code...

But still you need to maintain that code in the future.

And you still might be successful and hence be able to scale (which seems to be the problem with twitter)
