Are there any community activities or rituals or experiments we could try?
Preferably things that don't require special software.
As an example of the kind of thing I'm thinking of, Reddit has special "I Am A" posts (no, I don't think we should have those), or things we already have, like Quotes or Open Threads or Diplomacy games.
(This is a complement to the previous post about which topics we would like to learn about here.)
We could probably repurpose some of the Archive Binge software, although it might need work to reproduce the 'original spacing'. (Not that I'm convinced that's very useful. 1 every X days sounds better to me.)
Actually, it's easier to keep the original spacing, because then all you need is a database of the posts and their original dates, and some very simple math to do the query. To do "1 every X days" means you have to fake the dates, use serial numbers, or some other such rubbish in order to find which items to put in the feed.
