I followed Synereo for about 1.5 years. I got really disappointed. Two years of development, coins crowd sale, then campaign on Bank Into The Future - all they got a Chrome extension and Ethereum tokens. They promised a lot more than that, like a lot more. However, the end result is a joke. There are a lot of similar extensions, the only difference is - they somehow use Ethereum based tokens. Steemit has the same functionality, but also a lot more and was a lot faster to the market.
Synereo has a very bad habit of overpromising and under delivering.
If anything, I am looking toward the RChain - led by Greg Meredith, the former CTO and Synereo co-founder. They are working kind of Ethereum 2.0 - a blockchain and a special smart contract language that will actually allow to deliver all the promises made by Ethereum.
