I'm seeing questions on Ethereum being asked in the site "Bitcoin - Beta Q&A site for Bitcoin crypto-currency enthusiasts."
It seems sensible to either...
a/ rename the Bitcoin site to something like "Blockchain, cryptocurrency - site for technologies such as Bitcoin, Ethereum, altcoins, Ripple, Stellar, etc"
b/ leave Bitcoin as is and create a new inclusive site for the various blockchain/cryptocurrency initiatives.
I've seen Enlarge the scope to "cryptocurrency", not just Bitcoin. which asks a similar question, but that Q is 4 years old. Given the developments of the last 12 months, I feel it's worth re-stating the question with the 2 optional ways forward.
