Google Reader fetches our comment feed once an hour or so. Too long for some.
Scan this feed explainer, I have listed the PC-based feed readers. You can then decide exactly when to fetch our comment feed —-every 10 minutes, every 20 minutes, etc.
As for me, the blog administrator, I read comments and reply to them —-from within the WordPress system, on the “-comments”- page.
I’-ll log in as a simple subscriber, soon, and see whether one simple registered Midas Oracle reader could, from there, reply to other people’-s comments. That would solve some of the problems of the guy linked to, above.
