Some of the ideas that I've worked with at the early stages can be very far out. But none are as far out as space, I've been an investor in Zero Gravity, which runs the flights that let people experience Zero Gravity. And as a supporter of the X-Prize I've seen interest and activity grow.
Now, the first blog from space. Anousheh Ansari, one of the key supporters of the X-Prize, is now in space with the Russian Mir program. And she is writing the first spaceblog, which you can see at http://spaceblog.xprize.org
