I wonder how being bought out, which is surely a far greater occurence in the online world than the offline world, plays into this idea? If you consider that perhaps the major players have bought between 10 and 30 other companies then the opportunities are still abound, just different. I would tend to think that to most people being bought out or absorbed is a suitable alternative to the more difficult task of rising through building a sound business which could take a half-decade or more. Thus I would agree that yes, the model is different, but one is not necessarily more nurturing to opportunities than the other.
