The problem with working on a project like sql-docs is the large time commitment. It's not a small thing that one can just jump into unless you already have the skill set and domain knowledge. This of course is true of much of life's side work, hobbies, etc... The good thing about the project is that you don't have to master C or C++ or seven different program languages like some of code projects that are out there, unless of course you are write examples for them. It would be nice to see more examples of practical TSQL in the docs.
