Imagine a Snapchat + Reddit combo where you are able to send posts of text, links, pictures etc, but then they disappear after a set period.

The set period could either be a fixed time period (1 day, 1 week, 1 month, 1 year etc) or it can be after a certain period after the last engagement on that post (lets say 1 month after the last comment posted on it).

Thoughts? Open to improvement to this idea.
