There is clear need for discussion outside of GitHub.
As you know, Ondrej set up a mailing list several days ago: https://groups.io/g/fortran-lang.
In the meantime I also set up this Discourse instance.
Since there is considerable overlap between the purpose of the mailing list and the Discourse–general discussion about anything Fortran–I wonder if there is need to have both, and if there are adverse effects to having both.
There are people who will prefer the format of one or another. Email is lower bandwidth, but is also more rudimentary and lacks rich text features. On the other hand, Discourse introduces much more friction, at least in the beginning. I consider myself technically literate, and I find the Discourse UI quite busy and will take some time to learn.
A downside to email is that it’s more difficult to moderate. When there is clear violation of Code of Conduct, we can prevent the poster from sending emails again. However, violating emails that have been sent can’t be unsent or deleted retroactively. On Discourse, we have more control to moderate properly.
As this is an experiment, we need to try both and see what works. I think that we’ll end up using both, with somewhat different but also overlapping audiences on each.
What do you think?
