i see what you did there...
Sure, lets probe the library planet. Though, I also think we should send SOMETHING to Aiur, just to see how the Protoss' military reconstruction is going. Remember, we need to get ZergWorld back before we can crash it into Tarsonis.
Also, lets see how Bernie is doing (read: is he plotting anything, how are his force numbers doing, that sort of stuff)
Also, have we discovered anything good from monitoring the Terran communications?
