I don't think endorsements are meant to be true endorsements. If they were, LinkedIn would have written a weighted endorsement system by now (where an endorsement from someone with expertise in some field means more than, say, an endorsement from your realtor about your JavaScript skills).

It's just crowdsourced tagging with a different name. This way, recruiters who pay LinkedIn $10k/yr can more easily search profiles for keywords.
