There are some really good April Fool articles being published, as well as some very poor tries. Among the latter are the Guardian claiming to have adopted the Monarchist cause, and Ekklesia claiming the Church of England is rebranding. The best ones read as if they could well be true, at least for the first few paragraphs. The following are my top three (so far at any rate):
Skepticism is just another cult.
Scientology to be taught in RE.
Christian persecution and the great atheist conspiracy.
At least I think they are April fooling!
