Like is too easy, no emotional investment has been made, to do anything useful, you need to move to want. As noted in a previous post, social media wombats, those clicking a “like” button on your site in the hope that you will “like” them back, are breeding at exponential rates.
Nobody ever engaged with a proposition, or bought anything, because they “like” it. People become engaged with an idea, a brand, make a purchase decision, because they want to.
Nobody ever got marries because the “like” their potential partner, they do it for much deeper reasons, they “want” to.
