I like Wikipedia. It spans a vast breadth of human knowledge and is a good starting point for information about practically any topic. There is a fair bit of animosity against Wikipedia and I've encountered some of the strongest opposition from lecturers at Uni. While I understand their concern for its use as an academic resource (which it is not), it is as appropriate for general information as the Encyclopaedia Brittanica or Encarta or any other encyclopedia. Their focus should be on critical interpretation, not merely "Wikipedia bad".
