"Publicradiofan" sounds like a fantastic resource. Sorting webcasted programs by day and time is a very helpful feature.

One of my favorite syndicated non-commercial radio programs is "American Routes," which has its own website listing all the stations that carry it, complete with day and time of the broadcast. The problem is that the stations are not listed by day and time of their broadcast of the program ~ they're listed geographically by state, the list includes stations with and without webcasting capabilities, and there are LOTS of them. To find a webcast on a given day of the week, you have to search "manually" via trial-and-error through the whole long list. Too much hassle to even bother!

(If you're driving cross-country and want to find the nearest public radio stations, this type of listing could be helpful. However, not too many of us have web access in our cars!)
