How does StackExchange's mechanism address the difference between hard and easy questions? Honestly I want to participate in order to gain reputation but I'm seeing a big difference between the effort required to answer questions like these vs. questions like these.
Those who have the free time to wait for questions and then jump on them get their reputation raised but it doesn't seem like answering hard questions like the latter that take time to research and expertise to answer helps one gain appropriate reputation.
So is there any way that StackExchange's mechanism addresses this, or is StackExchange just another system that can easily be gamed by those with time to sit, wait and pounce on easy questions?
