Good move, @tipu. As an investor with a little over 3,000 delegated (spread across a few accounts), I was seeing a little less profitability than I wanted. I was considering not adding to my delegation.
I think that if you're getting way too many votes, you should lower the voter profitability and if you're not getting enough votes, you should raise the voter profitability. This will ensure a nice equilibrium. It will make investors the most money and allow the highest number of people to use @tipu.
Yep, that's the goal :) But it's hard because of the STEEM price swings which also changes the demand for the upvotes.
