Uber coders also know when to trash old code rather than update it to new standards. The culling of the herd to fit the available resources if often more important than keeping the sickly and poorly written code alive. It optimizes resource use for everybody: the code is smaller, less of it has to be maintained, etc. These skills are often overlooked as well since they are devlishly hard to measure.
This is absolutely critical for small companies to have. Otherwise the code grows faster than their ability to keep it up to date. They need more people doing more work than is necessary. This can push the small company over the edge of profitability (either there are too few people to do the work needed so sales suffer, or there's too few sales to support all the mouths needed to keep this extra code around).
Another trait of uber-coders is they have a global view. This global view often allows then do things much more efficiently because they know exactly the right level to do it. They don't have to do a lot of extra work "just in case" at the wrong layers. Poor programmers do the extra work and justify it as being careful, when they are only being wasteful to the project.
Large companies could benefit from these traits, but the way management is setup makes it difficult to properly measure these skills, reward the teams that practice them and to save the company money (which, in theory should be split between the company and the uber-coders). Sometimes the skills are recognized outside of the normal set of metrics, but often times they are not.
finally, if you think you are an uber-coder, it would be in your best interest to also be an uber-communicator. Not that you have to communicate a lot, but often times the right communications at the right times help more than huge reports that nobody does more than glance at anyway. The best prose for me often times is cut down by 1/2 from my initial drafts and 3/4 rewritten, but everybody is different. The uber-communication skills is what will get you noticed, promoted and have raises go your way. This is especially true if you can make other people more productive by merging the uber-coding and uber-communicating roles.
