Surprised that full list of #Unicode emoji's hasn't one to depict a network, let alone a decentralized network, or even one representing the internet.

I came no further than:
🕸️ spiderweb emoji U+1F578
❄️ snowflake emoji U+2744
Given that #Fediverse is owned by no one, that it is indicative of a large group of people (millions), and has its own culture in a similar way that countries have flags, and religions their own emoji, the fedi should have its #emoji
@humanetech the spiderweb 🕸 is pretty good I forgot that one exists
