I write lots of modules which look like this:

function get(index, callback) {
    if (cache[index] === null) {
        request(index, callback); // Queries datab

if you're doing callbacks internally, do whichever is suitable

if you're creating a module used by other people, asynchronous callbacks should always be asynchronous.
