Don't be so sure. Most people didn't think Facebook would make it. Facebook looked quite useless, especially when there were plenty of other chat services out there. Then there's Twitter which really no one thought would make it. Google was another big surprise.

I am an "old man" of the Internet. I have many more stories of sites which shouldn't have made it.
Thanks for sharing these insights.
