The Stack Overflow team has just announced a new service called Stack Overflow Documentation. Users can post examples of code usage and other can vote and edit. I'd like to have this for TeX.SX.
In light of the fact that most documentation people use to learn LaTeX is outdated or just wrong it would be a great advantage if we at TeX.SX had a community-driven reference. Also, many search online for LaTeX templates and find some 1000 line file which “includes everything”. A collection of simple examples with minimal boilerplate sounds like a great alternative to me and might succeed to convert people to follow the right path.
A simple example of documentation. That is the available template to fill with content.
<auhtor>a little more like the command. (can't correct it from here, in toronto for tug meeting.)
