It's not completely clear what you're building. Some kind of prediction market with social features? A question-oriented social network? It would help if the landing page gave the steps and sample flow for a question in time order, rather than just miscellaneous features.
You also shouldn't equivocate between "your friends" and "the community". Which is it, or both? Is it private, or public, or does it support both?
Are questions persistent and enduring, or ephemeral (e.g. Snapchat-style)?
Also, you're building a social application that wants user data, and you advertise "trustworthy" as a selling point. You need to be using HTTPS pervasively; Let's Encrypt makes that easy.
