Ironically, both Wilberforce and Hattie got their information from Wikipedia.
I am a regular user of Wikipedia and I have read countless things saying that Wikipedia is a horrible device and needs professional people to write and edit. I've contributed some to Wikipedia and what I've written is actually historic and relevant to the article for which it's talking about. I believe the actual point of Wikipedia is to get a general idea of what you are looking for and then use the external links or print references to further inquire about the subject. Besides, those opponents of Wikipedia are probably just mad because their article was speedily deleted by SmackBot.
