Today's tweet announcing this weeks edition of OBSERVATIONS Weekend was our 1000th! The paper can be viewed at http://paper.li/obspascal/1310800287. If you don't yet follow Pascal on Twitter, then we encourage you to do so to get more interesting stories. If you prefer your to receive our Tweets through Facebook, then that is another option since the Tweets are also available there. Twitter has a lot more because it also includes re-tweets from our followers, a number of whom are Pascal associates. You will find buttons to link to both our Twitter and Facebook throughout the pages of this site.
