90% of my portrait work does not have a model release because we have a verbal agreement that it will be on my website if I choose. Let's face it, if they don't want it there I will take it down anyway. I seriously doubt I will ever take a portrait of a person or family that I will want to sell to a magazine etc.
All weddings have a model release as part of the contract, but again.. if they don't want to be on my website I would not put them up anyway.
So, my answer is model releases are really a waste of time
