Developers, Developers, Developers! Very important. I wanna see how Tezos crowdsale goes. There's some very high profile VC's that are coming into back it. Its hard to tell what advantage it may have now with OCaml and its governance system. If the system is truly more secure from bugs and 0 risk of chain splits then I think for some very high level use cases developers would choose to build on Tezos instead of Ethereum. Since blockchains are each their own economy I think will see several large smart contract platforms that make it long term. Several large Social media blockchains too.
