I know there are quite a few readers who use various newsreaders (Google reader, Thunderbird, Opera, etc), to read this blog. I myself use Thunderbird to read the feeds of the blogs I follow. For us who have a feed reader, regular days of posting don't matter so much.
But are there many other readers of this blog who use a regular web browser, who need to come to the website to see if there is a new post, and for whom it would be helpful if at least one post were on a regular day of the week? (I couldn't necessarily write on that day, but I could try using the post scheduling feature, assuming it works.) Feel feel to write a note here if you would like to see that kind of regularity.
