"Space" has been measured to start at 73 or 76 miles depending on which science experiment you want to accept.
So are people taking this flight because it's the wonder of science or for bragging rights? Because if it's for the wonder of science, well science says you aren't in space.
(and really, if there is even doubt that the height you are going to is actually "space" then what the hell is this nonsense about? Let me know when you can do at least one orbit of the planet and then I'll say you did something extra special for spending all that money)
The "Hold down the left mouse button to start moving" line seems problematic to me, as are the other "mouse" references. I have not has a mouse for year, nor do I have a left mouse button. At least some visitors will be (in fact, have been) on mac laptops or touchscreen devices. I'd recommend something along the lines of "drag the page to move around."
Yes, true. But, I think, social networking websites was born just due to lacking of social interaction (among real relationships) on web while people was spending more and more time on it for searching valuable information. Facebook just brings social information in real life on web and make social interaction much easier (although I think it only keeps us further away from real life).
I'm in my 30s. My social group is mainly urban and mobile. It certainly seemed that vast majority of people around my age were on MySpace, and I say this as someone who never actually joined it with a real account. Incidentally, the same people who used MySpace heavily are the ones whose posts fill up my Facebook wall. In fact, most of those people were also on friendster.
Also, I have a relatively large family, many of whom are on Facebook. A year ago they were trying to use Facebook for family notices and communication. These days they've gone back to email. Everyone has email, but not everyone is on Facebook, not even among those who have already joined at one point.
As long as you can only do facebooking via Facebook, there will be people who aren't connected to it.
