Bummer. Here are the 2 questions you can answer for me?
1) How would describe the purpose of Confluence to a non-technical friend in the simplest terms with the fewest words?
2) If Confluence was the "offspring" of 2 other tools you use for work what would they be? For example, a fax machine is the "offspring" of a telephone and xerox copier. *
