question-answering

What today is the best answer for any given question, yesterday was not available and tomorrow will be obsolete. Especially when we're talking about software development.

Here is an example for you (there must be thousands, this one is absolutely imaginary):

Q: What is the best way to implement autocomplete in javascript?
A: (2000) Whut?
A: (2007) Write a custom ajax function, display the results after processing
A: (2011) Use this plugin: http://jqueryui.com/demos/autocomplete/ (nono, I'm not a jQuery affiliate, actually I prefer MooTools)

What would be your recommendation to introduce versioning for Stack Exchange questions and answers? Is there a need at all for that?
