Poynter has a nice list of ‘Letters to the Editor Blogs’:

“Examples include the Decatur (IL) Herald-Review, the Tacoma (WA) News Tribune, The Australian, and The Economist. In my own town, the Boulder (CO) Daily Camera letter blog recently garnered well-deserved praise from BusinessWeek blogger Stephen Baker.”

Author Stephen Baker also suggests some features he’d like to see, including a simple domain, cross-links, allowing HTML and even recording voice messages for mp3 distribution online.
