I have some questions.
- If it uses Solidity instead of Wren, how much will be the difference in performances? Is it too low to run apps in Steem as well?
- Can Solidity easily ported to Wren?
My point is with regards of marketing. If Steem can adopt Solidity with much faster and cheaper than Ethereum, we can absorb Ethereum's DApps and their developers very easily. "Same DApps on the faster and cheaper platform" will sound really attractive slogan for developers.
If Solidity vs. Wren is like Android vs iOS, my suggestion is like iPhone 4 (Ethereum) vs. iPhone 7 Plus.
