>A basic spellchecker is extremely simple to implement

That reminds me of this article: http://prog21.dadgum.com/29.html "A Spellchecker Used to Be a Major Feat of Software Engineering"

[lifeisstillgood]

Every time I read a norvig article I can feel myself get a little bit cleverer

Edit: And dumber, until I work through the examples twice

NB Chrome's spell checker has an edit distance of one. I learnt something useful and immediately applicable from norvig - I tell you this guy is great :-)
