Really - I looked it up.
And the data was confusing, but the show wasn't bad - it even had a computer in it.
Myouterspace.com is, in the captain's own words, '... a Sci Fi Social Network for those with a passion for the arts.'
But that is exactly why it won't catch on. The reason why Facebook is so popular is because -everyone- can use it.
Originally not many people could use facebook -- it was only for people in college. There's no reason why Shatner's site couldn't include more people later, but honestly, (and as other people have already said) I don't think they needs to include everyone to be successful.
Apparently pictures of space are cool again....
What? Pictures of space are always cool!
