I haven't watched the Weather Channel lately (but I do have that desktop thingy that I downloaded, not so long ago, that I like so far). However, from what I'm reading, I'll take your word for it. Having a channel on the weather should be straightforward to program but, it seems, some need to make things unnecessarily complicated.
Anyway, if NBC has to tinker with a cable channel I would prefer that it be Versus. Other than hockey, skiing and cycling, that channel is basically an empty vessel, basically airing whatever counts for "sports" until something more worthwhile is aired there. If NBC can keep the rights to the Olympics, let Ebersol program that channel to see how well he does it. The Sports department is, right now, the "best" part of the actual NBC.
