I am not really interested in all the twitter/app.net hoo-haa but I find it intriguing that we are at a stage that one guy develops a product and charges $50 for it. And the rest of the world mocks him for not making it free.
They are mocking it because they think it's a privileged network only for people who are willing to pay the grand sum of 50 US Dollars. It was the same story with svbtle. This smug sense of entitlement is frankly disgusting.
Then once he became popular what does he do? He built svbtle, a blog network of bloggers who all have pages and posts that look identical...
I also avoid the greater-than-thou grouping.
