I'm waiting to see who will first set up a system that stores all of reddit's posts and then checks them every X minutes/days for silent edits while posting a reply to it letting everyone know, or provides an API to check an individual post.

That already exists - there are plenty of "undelete" sites spidering and archiving comments on Reddit as soon as they are made.

and did they catch this?
