I myself called out a few people for being critical about something stupid but not every complaint deserves to be mocked.
On the Novacoin thing, I've heard it before and it sounds like a more valid critique than it actually is. Many wallets are derived from the same templates. It's a basic wallet, you don't need to reinvent the wheel there. Unless you're trying to do something unique with your wallets it's idiotic to waste time building one from scratch.
Neblio is built from a fork of a fork of a fork of a fork of Bitcoin. Many alts are derived from Bitcoin and that isn't a crime, nor is it indicative of a bad blockchain. It may eventually need an upgrade when volume gets really high (like Bitcoin/Ethereum/Litecoin level high) and I have been communicated with Eddy on a few possible solutions, none of which have ultimately been decided on.
The key to whether Neblio is unique or special doesn't necessarily derive from its origin code, it's derived from what is done with it. If two twins took vastly different paths in life, one could wind up extremely successful while the other floundered, despite being formed from the same mould. The Neblio developers vision is creating a blockchain platform that is both flexible and simple by creating a REST API base to give programmers the ability to code in their language of choice and then after creating V1 of their language libraries going back through and tweaking it to eliminate any code that is clunky, inefficient or difficult to work with for a more refined and elegant API suite V2.
Simplicity and flexibility are the purpose of Neblio, it sounds mundane but it's very much the opposite.
