Persistent posts (e.g., doing something right now) about tent.io HOT 2 CLOSED

I do not have an answer to your question but I do recognise that "Right now" or even "Happening soon" posts would open up lots of possibilities for cool, innovative new apps. You could have an app that's all about the present or about future events. How awesome is that?

Posts "expiration dates" are one of the first things we discussed when designing the protocol. Here's the challenge: most apps will ask for specific post types. So the status app won't know to ask for a new kind of post with shelf life. Every app that touches a specific type would need to become aware of new "duplicate" post types. We could of course add this to the general post schema (metadata on every post), but we're trying to keep things as lean as possible right now so we don't have feature creep in the early days.

There's an undocumented feature we'll be writing about soon called post versions. Basically posts are immutable, but you can publish a new version of the same post id. That update goes out to everyone in real time like normal posts and it's up to the app to display it in its feed in a manner consistent with its UI. So you can write an app that auto updates posts with a new version (or just deletes them) after a specific period of time.

We're still open to experimenting with expiration dates on all posts in the standard metadata (so it wouldn't have to be a different post type), but we'd like to see more developers adopt Tent first. Ultimately the community reaction will have a lot to do with this. In the meantime, try out delete (on a timer) and post versions (docs out soon!) and if those really don't work you can invent a new post type. We'll have more docs in the future on creating new post types, eventually with a whole JSON schema, etc which should make adoption a lot smoother.
