Guess it's slow for news in bitcoin world, but it's not uncommon to get several threads on one subject, especially when some fud or something controversial gets picked on. Oh, and most people don't search or even bother to check the front page before starting a new thread.
I think there is a plugin for simple machines where we can see similar/related threads just when we are about to create a thread. IF this forum feature will be installed then we might just be able to avoid such issues.
