Just to add a datapoint. I was reading the " Zulip API as Rust crate?" Reddit post, which linked to the “Zulip shortcomings” post on irlo.
I wanted to add a few things that I noticed in Zullip in the last couple of uses that could be improved, but I was also busy, so didn’t have the time (or energy?) to create a completely new topic, summarising the old one, and adding my remarks.
So instead, I closed my browser tab as soon as I saw that I couldn’t respond to it any more, and didn’t bother adding my suggestions.
Now, this might be good (if I didn’t want to spend the energy to create a proper post/topic, perhaps my drive-by comments wouldn’t have been particularly helpful), but it also didn’t really feel very “welcoming” to me, wanting to contribute a few minutes of my time to improve the Rust community (at least that was my hope), only to be greeted by an (unresolved) topic from a few months ago, that was already locked.
In terms of providing a welcoming environment as a Rust community, these small paper cuts feel to me like degrading that experience, perhaps not significantly so on their own, but taken together (not that this happens often in this community, thankfully!) they could.
