Given that questions about Ripple and other crypto-currencies are considered on-topic: Should this SE also cover questions about Ripple?
I think this site should be renamed to something like "Crypto-currency" or "Digital currency".
Someone in the comments said "I wonder if Bitcoin will become a pseudonym for cryptocurrencies in the public mind? Similar to iPod for mp3 player. If so, then this is a good name." but that's something to avoid as long as possible, it only causes confusion.
I'm aware of the "Actually, before the launch of the Beta the proposal was called "Bitcoin & crypto-currency" but SE staff decided to name it just Bitcoin." comment there, but I think that's a bad idea for that reason.
