A conversation can start buzz by imparting information listeners consider fresh news and can't resist spreading to others.
Your great idea or invention needs "evangelists." Exponential multiplication of your message is the goal. You want Mary to share it with her network, who each tell someone else, and so on...until voila! You're on Tech Crunch!
Be prepared for that message to morph as other enhance it with their own thoughts. And keep in mind that while buzz is at work on your topic, you can become the talk of the town. But without substance to back it up, your message may fizzle like a popped balloon.
Do verbal "product placement" to get your message on the lips of people "in the know" — movie stars (will that distant cousin married to a film star help you?); fashionistas (talk to that supermodel's agent); perhaps a conversation with editors of your favorite magazines or blogs will get things started. In no time, you could ahve the whole world talking.have
