Totally off topic, but I am genuinely curious what copyright law says with regard to these archive-type services, especially ones that alter the content, in this case by removing “clutter”. Awesome service IMO, I’d consider running one myself but don’t want to be sued.

Edit: I just read their DMCA section. It appears that they are saying “don’t submit content you don’t own” but then on their home page describe it as a service to remove ads (and other nuisances) from articles. In other words, they are trying to hide behind the DMCA while encouraging people to submit content that isn’t theirs. Again, I love the service but I fear for their legal standing should WSJ or others decide to pounce.
