As above, good posts are made yet within seconds are voted cold.
If you think about it, why do we need a cold vote? If you like it vote it hot, if its just OK vote warm, if its rubbish don't vote. Thats much reasier and takes away the abuse thats going on.
It really is dishartening to have a good post voted cold, even if it's only for a short time and leads to "why bother".
