The news comments section design has several holes: (1) If you 'liked' a comment, your name appears in the list under 'Thumbs up'. What about privacy of the 'liker' ? (2) If privacy is not a concern, why don't you do the same for 'Dislike' too? (3) Often it is easier to cite a url to support your claim, but Yahoo prohibits it, except if it is Yahoo url (Bias). There are java calls to validate the URL for its sanity, before publishing a comment; it's a shame if your IT developers don't know it.
