It would be interesting to see some sort of on-the-fly "topic" creation. For the AirBNB scenario, one AirBNB topic that would be a page that links to the 3 or 4 individual submissions currently ongoing (potentially with some comment previews, etc.). This would also cover the case of the same basic story (Foo releases Bar!) that gets picked up on multiple tech news sites and blogs. For things that are re-posts of the same content it might be best to be hand-curated. Where If the re-post appears to be gaining traction, pull out the old submission and discussion, but put it back on the front page for X amount of time (merging discussions from the new submission into the comment thread of the old one). For scenarios where the re-post is getting no traction then just kill it.
