Sounds like what Alta Vista was said to do so many moons ago.
As for what Yahoo did:
So, if you have a product which is frequently misspelled. If you're located in one community, but do business in several surrounding communities, having the names for those communities or those alternate spellings in your meta keywords tag means that your page is now a candidate to show up in that search. That doesn't say that it'll rank, but at least it's considered. Whereas, if those words never appear then it can't be considered.
