The issue there is that the value of those tags decreases if the majority just accept those tags suggested (which from what I've seen, most users do). There's no penalty to giving a tag, so if someone says "What to help one of your mates get a job by spending <1 second hitting a button" there's no reason not to (beyond your personal principles at least). To fix the system you either need to limit the number of endorsements you can give (e.g. you're allowed to give 3 endorsements (to anyone) for each contact you have), or have some way to force a comparison (e.g. is A or B a more competent Java developer in the context of Gaming?).
