Some topics are almost the same but not 99%. Have you tried to read from other boards? Different people can have same questions about bitcoin especially the new ones, and we give answers/thoughts that are almost the same with others. We are all interested to know more about it and sometimes posting a question is the most easiest way to find answers and gain knowledge from it.

Your observation is also the same with mine, even i  posted a topic like this few months ago at the meta.
