How would you find early adopters for an app to manage private identities

Thanks to other IHers, I was able to refine the copy on the landing page of Personalli.com - an app to help privacy minded individuals to manage their public and private identities.

Now onto the next step - how would you go about finding early adopters for such an app?

Thanks!

My learnings so far (to benefit other IHers) -

• Having a good copy matters, not only to have first time visitors quickly get an idea, but for you to be clear in your head
• Try the Ideas & Validation group on IH - people will provide valuable f/b
• There are several reddit subs that can come in handy too
• Talk to some of your friends - friends who can give objective advice
