I mean not specifically for IDF but for all armies. But the facebook-base intel is usually uncertain and foggy, also hidden under a large barrier of low probability of being hit, so not really worth exploiting. The soldier mentioned in the article probably did not include any Palestinians as his facebook friends and the probability of a Palestinian being a competent enough hacker to scan all facebook sites belonging to israelis automatically using a neural-network-based syntax pattern checker to hit that kind of intel is practically null (if Turks were fighting Israel, this prob would not be null but for Pals I am pretty certain it is null). So IDF's decision to calling the op off was a stupid decision. Not that I love IDF, I mean stupid from their point of view.
