An interesting concept and one that (to me) makes a great deal of sense.

I thought this was an interesting concept if targeted right.

An interesting concept that did not interest me in the slightest.

And that guy who looked at it, he said, hmm, this is an interesting concept.

Often they have interesting concepts but haven't worked out practical issues of production and distribution.

But that is not always the case, which is what makes the concept so interesting.

"It's an interesting concept, and yes, I would like to see it," he said.

It was full of interesting concepts about the relationships between supply and demand that really did work.

I think it is an interesting concept and everyone has a different situation and experience.

IT was an interesting concept, but there were problems.
