That is exactly why we started copying everything to that long blog thread that SE Mom started. That thread is our back up copy.
Unfortunately we may encounter copywrite issues with some articles so some have been doing c&p and sending it to themselves as a backup. I haven’t checked lately to see if the interview article with Obama after he was named editor of the Harvard Law Review has disappeared but will check tomorrow and save it if it is still around. That’s the article where he had claimed his first two jobs after graduating from Colmbia enabled him to pay off loans for his second year at Oxy and the two years at Columbia.
