>Is there still a lot of value using IRC in general?
weird question.
it's a chat interface. there are people to chat with on IRC.
Is that a valuable thing to you? Who knows.
If the question is "Are there still people that use IRC?", then "Yes.".
I know it's probably a 'mover-and-shaker' HN thing, but not everything needs to be rephrased to compare against value/time.
