Yammer CEO, after just a month of acquisition by Microsoft, has commented on Facebook that there aren't many ideas left in the Universe that : 1. Haven't been noticed by Big Internet companies, 2. Are capable of being proven and launched for ~ $5 million 3. Can survive the onslaught of the bigger companies once they 'understand' what you are after? There's some truth in the argument. Given the way Internet is evolving, communities are being isolated, innovation is being 'sued' by the major corporations under the name of patents infringement and so on. There's no end to human creativity; yet the law industry seems to be working to make sure only a few major corporations get the benefit. Do you think there aren't any ideas left that survive all of the above?
