Dave Winer has a good comment for anyone questioning the web:
So when they tell you they know for sure that the web is dead, or that everyone wants to host their blogs in locked-up silos, or that you can't build a great open social net on RSS, you might want to lower your glasses down your nose and look out over the top and ask Reallly? Are you sure?? ;-)
Nothing is certain in business. For every success, there are many “sure thing” failures.
I posed a question on this week’s Core Intuition as we were talking about Automattic’s upcoming .blog domain name registration. The gist of it was: what is more likely to survive for the next 50 years, Twitter or .blog? Twitter is huge, dominating the news and seemingly unstoppable, but social networks don’t have a great track record. I’d put my money on a new top-level domain, both because of the vision of empowering users to control their own content and also because domains were designed to last.
Companies aren’t exactly designed to fail. But that is their default outcome.
