The Wikipedia Knowledge Dump (or WikiDumper.org) is that heaven for articles that don't meet Wikipedia's exacting standards. While they frequently conform to the syntax of an ideal Wiki article, they are often of an extenuating self promoting nature (note the number of porn star biographies) or simply don't meet Wikipedia's rigorous standards.
