Not sure where to put this... but I noticed now that others are creating communities in this instance that I wasn't subscribed to any of the ones that were created after I had joined. Might not have even been subscribed to all of them that had existed when I did - it may have been just the community that i registered under..
So I guess this is just a reminder to all to periodically check the communities list so you're not missing out on the new new.
In your profile settings, there is a setting for whether you want your default feed to be "subscribed" or "local". I do think subscribed makes more sense logically, but local is also there if what you prefer is just to see everything in the instance by default (until it gets noisy enough that you prefer to filter some communities out)
I've been leaving it on Active.. and it pushes the most recently commented on posts to the top.. kind of how we used "bump" topics in old forums.
Yea, I made the same mental association to older forum/bump logic, but I found it quite jarring that the date of the bump was not visible from the listing, so I couldn't really get a sense for how fresh the overall feed was, and changed it for that reason
