Exactly! The "ultimate meh" would be *the backbutton*. If you look at your hitcount, and you're getting far more hits than kudos... THAT's people giving "the ultimate meh". But, as explained above - kudos are PRAISE. It's meant as a way of letting the author know you liked what they did without having to type up and hit send on "well done" - reading anything else into it - especially something negative! - is ... very bizarre to me.
