I often link to the Althouse blog because it attracts some good comments. And even though she is in Madison, Wisconsin, she gets comments from all over. A recent post attracted three comments from the Commonwealth of Massachusetts.
Here is a blog post on comments. Well written. I got here via The Instapundit.
I would like to note that (1) the new "I am not a robot" stuff is making it harder, not easier, and (2) the lack of a preview option for comments on some systems is annoying to me. I make a lot of typos and spelling errors and looking at a final copy gives me that last opportunity to clear up mistakes. It isn't like one can go back in and edit comments.
