In my opinion we need groups, like groups for cars, Tanks, Roman history, holidays etc like in reddit or Facebook. Than you can come much better in contact with other people and stuff you are interested in also without beeing deep in bitcoin. And because it is you for example Hobby you know maybe mich more and can talk much more and therefore also get more upvotes and zaps which leads to more interest about this zappinh bitcoin Thing. Also for the Rest it is also mich nicer to have such groups for given reasons
