It depends on the law of the land, but yes, absolutely! A blog is as good a form of publication as any, and it's not the medium but the message that gets punished.

Sure, those things can be printed out, and shown to whomever, by whomever. I'd always becareful, just remember the truth is always the best law.

Of course. Libel and slander are not limited to printed media, or formal media outlets. If you spread a rumor that the restaurant next door feeds dog meat and know that it is untrue, you can be held liable for any and all financial damages. Bottom line: You are responsible for what you say. Freedom of speech does not mean that you are free from responsibilty for the consequences of that speech.

Despite what people would tell you to believe, the first amendment covers your right to say whatever the hell you want, Period. Libel and slander cases are almost always LOST by the person bringing them forth. The first amendment is usually invoked and it pretty much destroys the libel or slander case. The standard of proving libel/slander is very very high. If I said something that was 100% untrue about your personal life online, and your boss saw it and fired you, you still couldn't win that case in court. You have to prove the statement was indeed untrue. If it was something about your sex life, that involves parading all of your former and present sexual partners. Then you have to prove that I intended to somehow damage you with the comment. Posting in a public place like the internet doesn't prove that. Sending a written memo to your boss would. If you need evidence of how hard it is to win a libel or slander case, look at tabloids. They print whatever they hell they want about celebrities and such, and you know what, nobody bothers fighting it because they can't. The standards are so high, it's near impossible. People need to stop being afraid of these ridiculous laws and making up stuff about them and how serious they are and realize that they have the big fat 1st amendment protecting whatever they want to say.

Yes, only speak the truth and the whole and nothing but the truth so help us god.

I have honestly never done it but I suppose so, this must be contemplated in the Community Guidelines and Terms of Service, as it is a private company no such things as constitutional rights apply. Legal matters are usually within the Terms of Service.

As an additional question. If I ask on a message board... ''Is it true that the restaurant next door feeds dog meat ?'' ...then is this already Libel, or does it need someone to actually state it as true, rather than put it as a question?
