This is a small website. The number of pageviews a month can be counted in the low tens-to-hundreds. The amount of traffic this page receives or would not receive today isn't even a concern. To that end, I don't know there was any impact to this website's traffic by using the script that redirected browsers to SOPAStrike.
Today was about showing support for and trying to educate about the need for sensible copyright laws in the US.
SOPA and PIPA, in the current forms, risk the crushing of a number of forms expression via the Internet. Yes, some of these forms of expression are questionable in their adherence to US copyright law. Some forms of expression utterly disregard copyright as well as concepts of fairness and fair use.
Yet the amount of content and conversation on the Internet that IS covered by fair use and in compliance with US copyright law that would be at risk is significantly larger body of work. And this is free speach.
