Weekday afternoons, with people in offices or home offices, are a very different listening environment than weekends, when most people are much more mobile. Long form works when people are sedentary. Not so much when they're mobile, although segmented programming helps.
People will seek out music or special programming that they like, but you now restrict yourself to the existing audience, which is likely to shrink on Saturday and Sunday evenings. The available audience at those times is considerably smaller than Saturday and Sunday from noon to 5. Any idea of growing the Blues audience has just suffered a massive, gaping wound.
What it really sounds like to me is that Blues programming, which is VERY successful, is not in the comfort zone of the programmers at WNED. Their experience with music programming and talent is Classical music on WNED-FM. Moving the Blues is designed to slowly starve it of audience. The idea of "local music" on air during the afternoons on Saturday and Sunday will fade within a year due to "budgetary restrictions" and "lack of response". I can hardly wait to hear who will host those "local music" shows, and what kind of music they'll feature. The last attempt, the "On the Border" series, was amateurish at best.
