CONSTANT_NAME variable_name ClassName functionName

1. Naming things is cheap--have DESCRIPTIVE NAMES. It should read as close to natural language as possible, avoiding abbrevs. and in-house language when possible.

2. Functions should have one thing they do. Endeavor to have pure functions, so that they do not have side effects. Functions should be have a maximum of three arguments. Good functions have one or two.

3. Avoid being clever and implicit whenever possible.

// Define only one instance for server of buyer and distributor ids for reactive counts.
var BuyerQueue       = new Meteor.Collection(null);
var DistributorQueue = new Meteor.Collection(null);

function isBuyer (doc) {
    return _.include(doc.roles, 'buyer');
