- We save a nasty query from every new topic and reply. We can do this because we are in a transaction, asking the database what is the newest info would just return the post_id we just inserted
- editting is now far cheaper if it turns out the newest post has been editted.
- switch the globality of a topic (making it global/unglobal) is now cheaper by a lot. If it turns out that we have changed the universe in any important way we can easily fix things much faster than before.
