Haiku's IRC channels have officially moved from Freenode to OFTC. https://www.haiku-os.org/news/2021-05-19_haiku_is_moving_to_oftc/
@haiku Hopefully one day there will be an official Matrix server))
@vazub You can already join via the Matrix bridge: #_oftc_#haiku:matrix.org
@waddlesplash I know and I do, but this is not exactly the same experience anyway.
This is a brand new server run by the main developers of the project as a spin-off of mastodon.social It is not focused on any particular niche interest - everyone is welcome as long as you follow our code of conduct!
