If SOPA passes in anything like it’s current form, it would almost certainly mean the end of reddit. It may not happen overnight, but we have a very small staff (~11, mostly engineers), and even dealing with DMCA stuff is a big burden for us. SOPA would make running reddit near impossible. And we have access to great lawyers through our parent company. I can’t imagine how smaller sites without those kind of resources could even attempt a go at it if SOPA passes.
