1. I would remove the penalty from posting to Leofinance from other frontends, and instead pay in staked LEO instead of liquid LEO for those users. That will give those people a direct incentive to become more intertwined with the main community, and take away the disincentive to get involved to begin with.
2. I would consider making multiple main feeds for LeoFinance. E.g. Main, Fiat, Crypto, Games and DeFi. Each feed would have a somewhat different logo and would focus more specifically on these main crowds out there. The main would combine the best from all others.
3. Have a clearer policy on what gaming content is appropriate for Leofinance, and stimulate users to share that content here (there's a huge body out there).

Just a few ideas :).
