The forum is not similar to a school. It is a school. Infact, how many schools teach what we learn here? It does not only have to be bitcoin lessons, there are other aspects of this forum that you can learn other things that are not bitcoin related. Politics, religion, gambling ethics, relationship coaching are all there. Just name it. And it also provides financial tips for keeping the body going.
Each user can choose their own interests in the forum from the start, so they have some freedom about that. I mean every user can learn about bitcoins, wallets or rather be a technical user. Several others have an interest in contributing as scam buster, spam buster or whatever, and there are plenty of interests to choose from.
Learning is not only limited to one thing, and in general, this interest must be owned from the start. Focusing on interests will allow users to thrive on forum, and lots of people have proven that.
