Yes.
That is my main reason for trying out project board. Even with just a few people trying to coordinate the devroom it can be useful for everyone to get an idea about the status of tasks.
In case of times where we feel like one person might be unable to complete a task on time or not being responsive it’ll be easier for others to jump in and get it done.
And for things like the CfP or other things that we need a consensus on I can copy the relevant info onto discourse.
The difficulty with discourse-like thread I imagine would to be find the correct post with the latest updates.
