Creative - you have to put quite an effort into posting a product, preparing comments describing your product, and engaging people.
Research - research examples of successful launches and what should be done before and after (I wish I could have researched more about it).
Beneficial - product awareness, great feedback, and perhaps new clients/users for your product.
Curious (my 1st time launching here)
Frustrating (fool around to find out how to have a good pre-launch campaign)
Exciting (can't wait to see how it goes)
