The only reason I look to see if anyone throws a star is that, it is about the only way you know someone read it! I don't get frustrated with it! I put more credence in the comment section. It is nice to know you helped someone just a little. The thing that frustrates me is the Tweens, and others that answer legal, finance, and other questions that need a real answer, when they are just guessing, or trolling.
Star is a source of encouragement for the people who answer the questions but it does not matter because the only thing that matters is to give helpful and Interesting answers to the askers :) I just want to give satisfactory answers to the people which really help them . I also like hilarious people and their answers .
Giving a star is just a polite way of acknowledging someone's answer, if you do not think the answer merits a star than don't give one; but to Ask a question and then totally omit any acknowledgement, be it a star or comment, is just careless and rude in my opinion. It really doesn't take much of an effort.
I feel common courtesy is appropriate and needed in this instance. The person with the question is asking for people to help them. In turn, when someone takes a moment to help the questionnaire, they need to be acknowledged. This pertains to answers that are helpful. Some answers may be fun. Many of us have made great friends through Ask.com. It's always nice to see their names show up on a question you have asked. As a general rule, I think they should be shown common courtesy. Isn't it still "common" to show appreciation or support your friends?
