Heres a recommendation.
The hot and cold system is easily flawed by people who click either as a hobby without reason. Wouldn't it be better if, just like Yahoo answers, a reason must be stated for your hot or cold selection. Then and only then we would be able to see why others have chosen either hot or cold rather than giving members a loss in confidence that the hot and cold system is as accurate as it should be. Kids are off school, they enjoy degrading deals. Heck, i bet competition from other companies is leading to a few minus degree scores.
Give each user a reason box below the heat selection. They must fill in the reason. It takes seconds. It gives members a good read. And the comments that lead afterwards will turn more positive thus not aimed at complaining about the current rating system.
Just an idea from a happy Hotukdeals member. One little change equals alot of happy faces.
I've got to the stage where im not sure that clicking a cold deal will be a bad deal. Imagine how many others are doing this?
Bye for now. Happy new year.
