Edit, due to the low meta activity: Everyone involved with this site, please take the five minutes and fill out the form at the bottom of this post and state what you consider on- or off-topic.

Edit 2, don't forget to vote up (or down) the answers you prefer most (or least)! We need to find consensus on this for future reference.

I think it's time to draw a line between what is clearly within the site's scope and what should be considered off-topic. With a constant flow of more than 10 questions per day, we do not need to reconsider to broaden our site's topic and it turns out it was a good idea to launch an Ethereum Stack Exchange test balloon.

Usually, it's of a better style to ask multiple questions in multiple threads. However, I want to make a rare exception for this discussion because I want all information in one place for future reference.

First of all, I want to list items where I think is consensus about that they are clearly on-topic for this site. If you want to dispute this, go ahead.

Ethereum Core Infrastructure

Ethereum (The Blockchain Protocol)

Ethereum Virtual Machine (EVM)

Solidity Programming Language

Serpent Programming Language

Whisper (The Communication Protocol)

Swarm (The Storage Protocol)

Native Smart Contracts (Ethereum)

Native Decentralized Applications (Ethereum)

Now, below starts the actual question part. On top of the items above, what should be considered off-topic and what is still on-topic for this site?

Stand-alone Ethereum Forks

Any Ethereum forks based on the Olympic, Frontier or Homestead versions: They maintain their own public Blockchain, using the Ethereum Virtual Machine (EVM) in any form and most Ethereum tools are compatible with their implementations. For example: ShiftNrg (SHF), Expanse (EXP), SoilCoin (SOIL), Krypton (KR). Are Ethereum forks on-topic?

Projects that implement the EVM

Blockchain solutions that support the Ethereum Virtual Machine (EVM) but are either not related to Ethereum directly, e.g., offering own solutions or only deploy private chains for customers. For example Eris Industries or Tendermint. Are Projects that support the EVM on-topic?

Projects utilizing Solidity or Serpent

Blockchain solutions or Toolkits that support Solidity and / or Smart Contract development but that are not related to Ethereum in any way. I don't have any use cases handy, but there used to be a question about when not to ask solidity questions here.

Smart Contracts and Frameworks

Blockchain solutions that fully support Smart Contracts but neither implement the Ethereum Virtual Machine (EVM) or offer Solidity programming language, e.g., Hyperledger, OpenBlockChain, Lisk. Are misc smart contract frameworks on topic?

Distributed Applications and Storage

Are questions about distributed applications or storage which are not related to Ethereum or Swarm on topic? For instance, IPFS used for storage in many cases.

If you answer, please include all points from above, maybe use a template, and try to draw a line somewhere.

Copy & paste template:

- Ethereum Core Infrastructure: on/off-topic, because ... - Stand-alone Ethereum Forks: on/off-topic, because ... - Projects that implement the EVM: on/off-topic, because ... - Projects utilizing Solidity or Serpent: on/off-topic, because ... - Smart Contracts and Frameworks: on/off-topic, because ... - Distributed Applications and Storage: on/off-topic, because ...
