Re: How about an 'Un-Like' button...
yes, 'disagree' would maybe be a gentler slap :-).
I only suggest the 'un-like' to give opposing symetry to the 'like' button.
I guess it's a slippery slope, 'like', 'un-like', 'disagree', 'ok-with', 'sort-of-agree'...
to many button choices... or maybe a radio button with 1-5 (disagree strongly, disagree, don't care, agree, agree strongly). you see that on alot of survey forms.
