I'd never heard of it. Looks cool. I'm glad someone cares enough to create a free alternative.

Ultimately the reason anybody still uses IRC isn't that they prefer the limitations of 512-char ASCII messages, it's that IRC is the only protocol that succeeded in building a network infrastructure without being, as was put elsewhere in this thread, a proprietary walled garden.

Major corporations have been trying to "de-commodify" chat protocols for decades -- millions of dollars has been put into it. It's something that ought to be fought against actively.
