I've been requesting a 'dating room' in the Water Cooler on Elance for many years. Nothing ever came of it. Although to keep the dream alive, a lot of my Elance metaphors relate to dating. I think that almost any difficulty somebody has in understanding freelancing, Elance or Upwork can be explained using some kind of dating site or singles bar analogy.
Apart from the whole 'money' part. Gets a bit murky then.
