Shaded: How about if we used some criteria like this:

Eight of the 20 should be from outside the United States.

Six of the 20 should be publicly using non-Microsoft OS's (Linux or Macintosh).

Eight of the 20 should be women.

Four of the 20 should be from "non-famous" blogs (blogs that aren't on the top 100,000 of Technorati).

Eight of the 20 should be developers.

Two of the 20 should be Tablet PC enthusiasts

Two of the 20 should be Media Center enthusiasts

Two of the 20 should be 64-bit enthusiasts

At least two of the 20 should be Channel 9 members in good standing (IE, top folks who are among the posters who have been members for more than two months).
