People may as well post if they have something to share, but I will use my votes on the stuff I really like. I am finding enough of that for now to use them up and I rarely give 100%. I do vote up comments too as I want to encourage them.
This latest HF ought to be better for many people, but they have to be active to earn.
Maybe one day Hive will be filled with celebrities who get all the post rewards, but building up some HP allows us to earn from curation anyway.
