I really like the suggested conversations feature. I think it would be interesting if each of a wide group of friends could select specific interests, then suggested conversations appear just to those people who are interested in that class of topic. Looks slick as well.

Some questions:

- How do you make money?

- What's your privacy policy? How do you ensure message privacy (the app description calls it 'private')?

- Is it iOS only, or can I connect via the web, desktop client, Android etc.?
