Yes, this is true. We spell and grammar check the popular questions on the service in order to make it a more pleasant experience... I know if I misspell something on the web I would appreciate someone fixing it for me, as opposed to 10 folks attacking me.

In fact, that's the other big secret of why Mahalo Answers is having a fairly strong start: we don't allow obnoxious behavior. If someone responds with "why don't you google it n00b?!!?" we delete the response and warn the person once before closing their account.

We have a "no a-hole" rule basically. I'm going to do an email newsletter about the things we've learned with community building. My email newsletter is at http://www.tinyurl.com/jasonslist if you're interested.
