> I see the real answer to this as the gTLD program: radically expand the number of domain-issuing entities and normalize companies operating on something other than .com.

However, that has another problem in that it increases the opportunity for fraud via. The benefit of a small number of tlds is that the most memorable part is typically the most unique and provides human-distinguishable identity, but that's out the window if you've normalized mybusiness.com, mybusiness.biz, mybusiness.business, mybustiness.bz, mybusiness.bus, etc. Typosquatting still exists with .com, but it's far more manageable that the above.
