Agree with you on your 3rd paragraph on the deafening silence by the opposition important issues.
I do however feel that one dismisses the internet as a valuable communication platform and forum at its peril. It just too valuable to ignore. Merely using it as a homepage cum webite is not enough.
While I think you have described the ideal situation, the reality is not so simple. The opposition not only has to engage on the net but also have to deal with the distortions and twists of everything they say. The former doesn't take a lot of time, but the latter does. I do not know how much resource the opposition has to deal with that.
