I totally agree. I think we need to decide whether we're all thinking in Glicko points or Kyu/Dan ranking.
Up till now we've all gotten used to thinking in Kyu/Dan points, and we know what 15k roughly means.
What does 1200 glicko points mean?
Glicko points are a wonderful implementation detail, but users think in Kyu/Dan ranking terms. While it's been fascinating to see the inner workings, I think that the interesting information (such as "how good is my opponent at 19x19 correspondence?") should be expressed in Kyu/Dan.
