The one thing I really like about PBS is it's kids programming. I don't have to worry about my son watching it and being bombarded with advertisements. If PBS went away or started ads, we'd go to just watching DVDs, which is fine I guess.
In a broader sense, I'm OK with stopping the funding. I really wish that the government would focus on cutting costs in places that it would make the most impact, like defense, but any little bit in the right direction while not cutting vital services is fine with me.
