In my opinion, several of the posts in this thread should have been prefaced with a statement along the lines of, "I am not a (subject matter expert/lawyer/etc), but in my opinion..."
Not trying to single anyone out with this comment, because this happens quite frequently, but when speaking about certain issues (safety-related, legal, etc., in particular), I am concerned that, without such caveats, there exists a real danger of spreading inaccurate information, to the detriment of the community.
I don't think anyone should rely on the advice from an anonymous post on the internet, but when someone makes a conscious effort to post about certain issues (i.e., safety-related, legal, etc), I personally believe that the individual has a duty to post responsibily, or explicitly state that he/she is simply stating an opinion, so as not to spread misleading or inaccurate information.
... again, this is just my opinion.
