The recent rise in long-term Treasury rates prompted lots of commentary. A selection:
Front lines: John Jansen, Accrued Interest.
Bearish (i.e., herald of a rollover crisis): Yves Smith, The Economist, Niall Ferguson.
(For those concerned about such things, this post explains what a rollover crisis is, along with its probable effects; the comments thread of said post also contains an interesting exchange between Delong & Roubini.)
Setser on the Foreign CB Aspect: 
Bullish (i.e., higher long-term rates = return of confidence): Models & Agents, Martin Wolf
On the Fence: Duy, Setser, McArdle .
Inflation v. Deflation: Related was the debate over whether inflation or deflation was more likely in the future.
