How do you think we should handle the US Senate's filibuster rules?

As this Washington Post article explains, on the first day of the new Congress, the Senate will review the rules the last Senate operated under. Rule changes need only a simple majority vote to be adopted. They cannot be filibustered by the minority. After years of growing abuse, pressure is intense for some change to limit the minority’s power to promote permanent gridlock by filibustering virtually every bill and appointment brought before the Senate.

How do you think the rules should change? Should they take the filibuster back to what it was in the famous Jimmy Stewart movie Mr. Smith Goes to Washington when a Filibuster required that the minority hold the floor and keep speaking, abandon the filibuster altogether, keep things just as they are now, or perhaps you have a better idea?
