The words "Embassy" and/or "Ambassador" have nowadays a more flexible meaning:
"The word is also often used more liberally for persons who are known, without national appointment, to represent certain professions, activities and fields of endeavor"
If you are going to quote something please link. I looked it up and you grabbed it from here:
https://en.wikipedia.org/wiki/AmbassadorThe words Ambassador/Embassy are NOT interchangeable in the context of a standalone building that is a hub for Bitcoin enthusiasts by Bitcoin enthusiasts. This project is neither official or unofficial, it just is. There is no distinction in Bitcoin because there is no such thing as centralized authority. This name rejects that.
Even if there are alternative use cases for the word you can't separate them in this context from the word's diplomatic, official derivation. It's confusing to most--not to mention it sends the wrong signals... you probably don't want to invite insinuations of centralization or that this is some extension of the core developers or Satoshi himself. It's oxymoronical, and I say that with all the respect in the world.
Conceptually (and practically) this is super exciting. I applaud you guys... thanks for making this happen. Just please, no embassy.
