I decided to be even more active now as it is time to build relationship - your vote still has same power but the reward pool is simply smaller, votes become more visible when the pool is growing - you might see the rewards on your posts of the last 3 days is growing everyday a bit. Reputation is stagnating i think based on the whale experiment - if some whales (or people with her rep) up vote you the chance that gets down voted is quite high - that would be my explanation.
