Thanks for the note.
I recently decided to change how I handle this; I’ve created the account “EA Forum Archives” and will publish archival posts from there. They’ll still show up in Recent Discussion, but people will get used to seeing them and be able to skim past them as they see fit.
Sounds good, and if those Archive posts might be novel and useful for enough readers you could consider also adding them to the Frontpage.
Besides, maybe at some point one could also consider enabling users to “unfollow” individual accounts so those don’t even show up in Recent Discussion if one isn’t interested.
