While putting up an interstitial to warn about SOPA/PIPA and get people to call their representatives would be almost as effective in its short term impact on those 2 bills, I think completely blacking out is a much more effective long term strategy. The chance that politicians would try something like SOPA/PIPA anytime soon, if all major sites go dark in that day, is much smaller. Showing an interstitial could be a form of protest against anything. Going dark is clearly a form of protest against censorship. And I don't think any politician will want to be associated with that in the future.
