I didn't think you put them in there. People like to make statements by adding keywords; I guess it amuses them. For whatever reason, this thread has achieved the highest keyword count I've ever seen.
Putting in only 'Iraq' is almost pointless since you will get so many returns- thousands- that you still won't know which article, or in this case an entire thread, to read for data you want. What if you are looking for references to diplomats? It won't turn up unless the word 'diplomats' is entered. What if you are looking for Fulbright? If it isn't in the thread's keywords, you will miss the info contained in the thread on Fulbright.
