Many times a week I find myself laughing alone at some of the most stupid reveals as I cursor over some blocked out text. I feel that this solves some of the problems with jokes in text form; by allowing for some of the dynamic of a vocalised joke to be achieved.
Many people say that I'm obtuse. I disagree. I think I'm a cute.
At this point in time there's nothing much to be gained by actually sending manned spacecraft. Most experiments can be carried out by robots and data sent back to Earth. Plus you only have to send the payload there so theres no extra weight from the fuel you need to come back let alone the shuttle/craft. Manned missions are more of a political statement than a scientific need.
