I think communities could be a big plus for Steem, but it's been a long time coming. Not sure about the value of light accounts. I can create accounts with RCs, but I don't see a way to do it through the Steemit site. I've used SteemWorld. There ought to get a method that lets you create an account and get the keys to the new user without you seeing them. I thought that some sort of 'sponsored' account creation was going to be added. I will delegate to people I bring on board who can add value. Just make it easier.
