I noticed that CryptoZoidberg basically stopped updating Boolberry in late 2015, as seen here: https://github.com/cryptozoidberg/boolberry/commits/master. Since then, the currency has almost completely flopped.
What would happen if the same thing occurred in Monero? What if MoneroMooo and Fluffypony and the rest simply lost interest or had other sudden priorities, and walked away?
