I wouldn't ignore it. There is the real possibility that there is too much capital being pumped into early-stage companies, and when they fail, there will be too little available to all. The best way to insulate your business from bubble economics is to find a profitable business model that is not reliant on the exuberance of others, and not easily replicated by someone else. Someone likened Google's other businesses as the moat around their search castle in another thread. I would recommend that everyone think about how to build their own castle that repels competitors as well as the effects of economic externalities that are outside your control.
