These days facebook group is one of great place to learn and share info, and yes there is Bunch of it (I mean it, there is really a lot Facebook group out there!) but the one that really good to learn, share or even ask question for online marketing related is quite limited, most of them are closed group so you need to tell your reason why you join and what can you contribute, etc (depend on the admin of the group).
