While implementing some fuzzy search would no doubt be great fun, the human-driven spell correction in titles and body of nodes is probably less difficult to implement (since it already works), less error prone and... more useful: a node with good content but bad spelling (due to lack of english, stegalhenics or such) will get fixed; nodes which show a lousy attitude towards the community (not caring about how it's written, just "gimme") eventually will not.

Let them rot in darkest corners of the database.

<update> Synonyms is another topic, though, and worth implementing.</update>
