Maybe that's because there isn't usualy the oportunity to do so? I do agree with Toreador that a 'like' button is essentialy the same as giving a photo a score - you're quantifying the extent to which you do or do not like the photo. If the photo doesn't make the grade, you effectively give it a zero, by not voting.
Personally, I like being able to express an opinion on a photo, be it good or bad (ok, that could be done by 'adding a comment' alone). I also upload photos of my own to let climbing friends see a record of our days out, rather than to get feedback from the UKC masses on the photos themselves, but it can certainly be interesting how some of them get scored.
This thread has reverted to a discussion on the merits or demerits of voting, whereas the OP was intended to question whether or not people grade their mark according the the 'arena' of a photo's content.
