You are only clicking on unanswered questions - the ones with an open button against them - answered questions have a blue filled button next to them. Answers, however, are just people's judgement and not necessarily definitive.
You could of course try answering a question yourself if you have any specialist knowledge or experience to offer.
The search box on the top right of the screen is often a good place to begin before you even enter a question.
Did you have a real question?
