One of the things I like the most about our community is that we learn from each other. I love reading and learning from everyone's answers- I have seen things done with
LaTeX that I would never have thought possible.
When finding a duplicate or related question, I'll sometimes link back to an old answer of mine and realize that either I have learnt a better way to do it, or the package now provides a different/better way.
Does the community regard answers as a 'snapshot' of the currently available resources (both knowledge and package interface) or should they be updated as and when either of these things change?
