Not only general idea. I leaked a lot of hints, use them.
Perhaps we aren't all as keen on the puzzles (generally I am - but perhaps like some others am just getting "tired" trying to keep up with this topic).
Personally I think that 100 TPS, a max. size limited blockchain and being able to do atomic cross-chain transfers (i.e. a trust-less P2P crypto-currency market) would be about the most relevant features to differentiate against other competitors.
High TPS, not bloated chain and decentralized crypto exchange would be huge.
