It's helpful to educate people, as always. But, I used to care a lot more about such rules than I do now. I changed my mind for a couple of reasons. First, English isn't native for everyone. Mistakes are made. In today's world, it's easy for people to move to another country, and easy to E-mail someone on the other side of the world, or read their web site. There's a very good chance that when you read something, it was written by a non-native speaker. Second, I think the only mistakes that really matter are the ones that fundamentally change the meaning of a sentence and add ambiguity. As long as I can figure out what somebody means, and there's nothing else it could be, I think it's fine. I can't think of a sentence where it is equally likely that someone is "losing" or "loosing" something, so I know what was intended. On the other hand, if you say "three" and you meant "thirty", that's a problem because I'm not very likely to guess what you really meant.
