I don't really use LJ much, mostly because I can't write things anymore and secondly, I just use facebook and thirdly i'm trying to avoid any Dark Knight spoilers! But I had a link on a previous post about someone I admired greatly, Dr. Randy Pausch. That link has bascially been his update to the World on how he's progressing, hadn't checked on it in a while, but the last two posts basically said that Randy was too ill to post and a friend would be doing updates for him and the last update was announcing the death of Randy on the 25th July.
I hope his motivational, inspirational spirit will have effected people in a similar way it did to me. The World just lost an amazing human being.
