thats true, i think that here there is a lot of useful information and you can get a lot of knowledge here, besides that i sometimes use reddit
agreed most of the best information is you can see here in bitcointalk.org that is why if you are newbie do not be lazy to search what things that you not understand in bitcoin for sure you will see here the answer in your question.
