What do y'all think about mailing lists and IRC as sole communication channels?
Say you want to contribute to a project and find out the only way to do so is by discussing the issue on IRC or the mailing list, then submitting the patch per email.
I totally agree longterm projects are better off using github or email.
Here is the crux for lively discussions using discord/IRC comes more natural. But whilst it facilitates easier flowing communication it fails to preserve it.
