well i never seen whats was wrong with the thumbs up or thumbs down version. relatively it all means the same. - + like unlike, but it never declares dislike, just unlike, strange word would be like unlove, or some other hookishly insane word.

you have a good point, where is the universal expression that would not be impeding on others brands, or piggy backing on what has already been established.

how bout a garbage can for 'not liking' something, anything, you can put anything in the garbage, see more

and a gold bar for liking, with possilby the term 'bank' emblazoned on the gold bar.....

yeah thats a difficult one andrew......
