So, to be clear, the following tend to be seen as problems by their interested parties:

  * withholding tons of domains to watch them go up in value means people can't get those domains (scammers, regular people)
  * registries do not make a high price when they sell high-value domains (registries)
  * there's only so many words / groups of words that are easily typeable (everyone)
  * reducing scarcity reduces the value of digital real estate (domain squatters / traders)

Which of these issues / values / interested parties are more important to help than others, and what, if anything, should change?

I, personally, tend to be in favor of reducing the impact of scalpers by increasing total available volume. As a consequence, I'm also willing to accept some terms for the registries that they get to set higher prices for the most premium of their domains to:

  * sweeten the pot for both registries and registrars to even support all these new domains
  * reduce a squatter / trader / speculator / scalper's ability to sit on vast tracts of digital land.
