True, but that hardly seems material. I'm an investor in Sia, I like the project. Whether or not it's implemented as an Ethereum token is nearly meaningless. To be quite honest, it'd probably be better if it was, that way it could focus more on its core competencies.

The term token is a generalized term to talk about the tradable asset on a blockchain. Bitcoin is the token on the Bitcoin blockchain. Ether is a token on the Ethereum blockchain, currently at a lower level than any of the ERC20 smart contract based tokens, but it's still referred to as a token.
