If you're not educated on SOPA, read up on it. Then, call your congressperson and tell them they're a complete jackass if they vote for this garbage. Government needs to enforce the DMCA better, not make more laws that are more broad and far over-reaching.
"Tomorrow, the US government will vote to have broad powers to block any site. SOPA would not only hurt free speech, it will choke off the internet workforce and its readers by taking down entire websites. Today is the only day we have left to have our voices heard. It's time to pull all stops - please make a call right now to protest censorship."
Update: I've decided that merely passing along commentary on SOPA from others isn't enough and I will be posting a full-length commentary this evening around 6pm EST. Be sure to check back on the main page for more later.
