I have noticed that many of those who regularly comment on my posts are getting increasing SP....that makes me happy. I know it is not all me, but it does help to know that I am aiding in accounts pushing upward.
Over time it all builds and I am glad to help when and where I can.
I have to say I've certainly benefited and it makes me quite happy to see the increased SP and the increased voting power that I can then share with others.
I hope to keep doing my part to help it move up.
The more you grow, the better it is for all of us on here.
