At version 3.0 and no clear indication of how they are able to monetize their "network".
Also focusing on user engagement, as they are narrowing down on solving needs that are a) painful and b) frequent. They want users they've already attracted to be firing up the app daily, not weekly or monthly.
User retention is probably the biggest problem they have now and if that is not squared away, no way can they ever monetize or be profitable.
