See http://en.wikipedia.org/wiki/Hulse-Taylor_binary. It was the reason for the 1993 awarding of the Nobel Prize in physics. What you failed to mention is the probability of LIGO detecting an event of sufficient strength during its time of operation. Events which are strong enough to be detected may be few and far between and it may be for that reason that it hasn't detected anything yet. E.g. what is the probability of to black holes colliding during the time LIGO has been in operation etc.
