For a long time, users have been able to submit microblog-style posts to link-aggregator subs (a.k.a. subcommunity, community, magazine, etc.). Some platforms such as mbin require you to select one for your post. Previously, I’ve thought this sub selection as a special hashtag for the post. However, I’ve recently been reminded that posts actually show up in communities as full-on threads. So what do you (or the threadi gods) consider to be proper etiquette in selecting a proper sub to make your microblog post to? There’s always !random, but that feels kinda worthless…
I’m assuming that this is about your earlier post that ended up in LW’s technology community. Microblog posts like that seem to be more intended for whoever is following you as a user. If MBIN insists that you also have to choose a ‘sub’ then I think it’d be best to put it in whatever it considers a dumping ground (ideally something that doesn’t federate out), so the ‘random’ magazine sounds about right to me.
