I agree with you and add one more point that each community should set some community account and each member should delegate fix % like 5% to that account. This account can grow at power at once and keep voting the content depending upon the quality.
It will bring more exposure to content creator and good content creator can give tips to other to improve their posting.
Recently, "India United" community wake up and I make pledge to myself that I will keep my 15% HP delegated to them, and after adding each 100HP, I will increase the delegation by 15. In long term it will become big delegation. (My thinking is that if I reach 5000HP and decide to delegate 750 HP to them, it will suddenly start looking like dent to my HP, but if I go by step of 100 earned ,15 delegated then it always look like increasing HP, because that 15 HP I will easily replenish in few days but replenishing 750 will become like big task for me.)
That's a very intersting approach. I think that delegating to a big community account is a good idea but the users should see a direct profit from it by getting upvotes for example. I believe you have outlined a nice long term strategy for yourself.
Direct profit: A % of delegation profit is going to paid back (in my case it is 80%)
Indirect profit: Exposure, you get exposure beyond your followers and that can convert to votes and more followers.
Delegation do not qualify for getting vote and you will be voted according to content quality.
