I just searched Google for 'Karl', and got pages with 'Carl' in them. No, bad Google! This is why I switched from Infoseek to HotBot back in the day. It's okay to ask me if I meant to search for Carl, but until I tell you otherwise you should assume that when I type Karl it's because I mean Karl and not Carl. And I'm quite capable of typing "(Karl OR Carl)" if that's what I want, so don't go using that as an excuse.
