Feedback at 5:00: Should People Be Accountable For Online Comments?

A Texas businessman says he wants the state's Supreme Court to order a removal of what he calls defamatory comments from the Internet.

Robert Kinney says his former employer wrote an online post accusing him of running a kickback scheme after being fired from a law firm in 2004.
A lower Texas court has already ruled the remarks should stay there, because otherwise it would be a restraint of free speech.
In a separate case, a Virginia woman was sued by her contractor for posting a negative online review of the work done on her on her house.  
Should people be held accountable for online comments? 
Should others have the right to sue if they don't like what's being said?
