Top Ten.

10.) Simplicity. The most compelling experiences are often the simplest experiences.
9.) Conveyance. Any compelling design must be conveyed coherently to evoke an experience.
8.) Attitude. The attitude with which you approach your audience sets the stage for their experience.
7.) Consistency. Staying with the topic, being flexible enough to bend to questions yet reform them to the original discussion.
6.) Acclimate. The peculiarities of your audience determines what is compelling.
5.) Maintenance. People get bored, a compelling experience is throughout time - not one instant; even if it occurs in an instant, its impact lasts longer. 
4.) Generalization. A compelling experience is something everyone can have. Be general to achieve the greatest amount of success, not everyone is a specified expert of bodies of knowledge.
3.) Welcome. To evoke an experience in a person they have to be open to it and thus happens when you're welcoming to who they are and what they bring to the table.
2.) Fuel. Once they're in your home, how do you treat them? And how do they treat you? A compelling experience is like beauty defined by Howard Gardner: it is an experience to be revisited.
1.) Compel. When it comes down to it, be real; be straight forward and address a person as a person - the force and power that comes of being confronted in the hear and now is the one thing that transcends every compelling experience for everyone.
