Whats it mean to star a question?

Question

Im not new. But i dont do this enough to not be new.

Answer 1

When you star a question, usually it means you find it interesting. If you want to answer a question and don't have time, you could star it and it'll be in your records to go back to. Like the guy above me noted, it also helps you find questions you liked that you may or may not have gotten to answer.

Answer 2

It just helps out ppl searching for an answer. How useful or interesting it is.
