If you say you think something then someone may be expected to ask you to explain your rational and you will have to satisfy them to gain credibility - "think" implies that you have been considering something tangible. When you say you feel something you get a pass - everyone knows that what you feel is your emotional response. Works great in advertising - that is one reason there are so many testimonials - and so few statements of fact.
At least thats what I think I feel. :-)
