Per your recommendation I did power up a low power user here that I thought was deserving. I see they got a power up badge (I already had one) and an extra 10 HP. It didn't do anything visible on my account other than in my wallet stating I powered up someone else.
I kind of like this though. Thanks for pointing it out as the first of the month. I will likely try to make this a monthly thing. I'm going to try to find people that are under 100 HP that I think are worthy and at least one of them a month, maybe more power them up by 10+ HIVE so they can get that badge and the bonus HP.
