A very good practice is to use a data set like this: http://people.csail.mit.edu/jrennie/20Newsgroups/20news-bydate.tar.gz
Segregating by date avoids problems with duplicate documents appearing in both training and test. It also gives you a standard split so that you can compare to other peoples' results.
