I'm the only member of my four-person household who doesn't regularly use Snapchat, the app created by Snap (NYSE: SNAP) - probably because I'm the oldest. Interestingly, the percentage of people in my family who are Snapchatters - 75% - is the same as that of all 13- to 34-year-olds in the United States and other developed nations. Think about that for a minute... Snapchat has won three-quarters of the audience that's most highly coveted by advertisers. And for 13- to 24-year-olds, Snapchat's market penetration is even higher, at 90%. These are the ages when people experience important milestones in their lives. This is the audience advertisers want to get in front of. But when I peer closer at the company's numbers, the picture gets more complex... Early investors in Snap are hurting bad.
