People may star your question, if they find it interesting and want to see the opinions/answers of the answerer's after them. they may give the question a star, and then it will go into their profile on their star list so that they can easily find the question.
You can see who gave you a star by clicking in that "show who starred" button on the right hand side if your page.
The link below may be helpful
Every time your question receives a star, you do not get any points. If they started giving points out everyone would beg for stars. You can remove or add your star simply by clicking on it, making it in active/inactive. If you give some one a star it doesn't take or add any points.
You can view your or any one else's starred questions by clicking on your/their profile and clicking on the "starred questions" tab.
If your question gets a lot of stars then the yahoo staff may review it and put it in the front page, so lots of people may answer it, then you will have a headache choosing which answer to pick as best!
I hope that helped!
