Not sure if you're trying to imply that information written by lawyers wouldn't have such a disclaimer. If so, that's nonsense. The language is there to make clear the site doesn't put its authors in a lawyer-client relationship with its readers, and directing them to retain a lawyer themselves if they want Advice they can rely on. No lawyer is going to offer free advice in a manner that makes them liable to every one of tens of thousands of readers in the event that the advice is negligent. (IANAL).
