Another user asked me in the comments section to my answer here why I combined so many approaches in a single answer. This made me realize we don't seem to have a clear consensus on if and when it is proper to post multiple answers.
I found this thread on the main meta:What is the official etiquette on answering a question twice? where the top voted answer suggests that different approaches should be posted as different answers. Others, namely @JeffAttwood and @Gilles, suggest that as a general rule it's better to post a single answer, providing the different approaches in one place.
So, how do we, the U&L community feel about this? When is it OK to post multiple answers to the same question?
