Actually. In all seriousness... the sentiment, "just look at it", is what the "like" button really ought to be. Not necessarily a vote of approval but an indication that "this is important, this contributes to the discussion, this is relevant".
Of course people will try to game it, just like any kind of upvoting--that's why the top comments on popular threads on e.g. Reddit are usually either dumb jokes or pandering. But maybe implying that it is worth looking at, rather than just a "yes! me too!" would change the dynamic somehow? Of course BB has a different culture anyway, so, I dunno.
The incongruity of a "hmm yes very interesting" button being a complete non-sequitur also tickles me.
