Surprisingly enough, whether it resonates with you or not, the conference folks reviewed and accepted your proposal because they felt it had merit.  :) So don't worry about it, some times those things that you take for granted and common knowledge are innovative and novel to others!  Those folks that read the description and choose to spend time with you that session have made a choice, voted with their feet, to hear what you have to say and take what you have to offer... It will be fine!
