Oh I dont know if I have used it enough yet to say, but I will try to answer:

• It's okay to make the design nicer, I promise.
• It should use Slashtags and Reputation features more deeply
• The jobs page should be priced per day, not per minute, and should have a 1 sat minimum bid.
• it shouldnt be custodial balances
• it should have more leaderboard features for users and post-types and timeframes, etc

maybe it already does some of these things or these are bad ideas, just riffing!
