I don't know the whole formula either. Ok, I don't know any of it. I just know the factors. I don't self-vote so I avoid the negative points. I try to give out lots of votes for things. I also try to leave informed comments on lots of posts, but it's difficult to get the points up sometimes. I hope you can get the 50,000 point mark though. That would be fun to see. We'd have to make you a cake or something for that accomplishment.
At the end of the day, if you're enjoying it, I think that's better than metrics. Unless metrics are the goal, in which case, get to earning. ;)
Can't remember who I've told this to, it may well have been you, so if I'm repeating myself, tell me—I tend to enjoy meeting and surpassing my previous attempts. It's the only competition I allow myself to have anymore, between me and me. So, I have lots of fun with the interacting, the learning, the meeting people I would never meet otherwise, and I also have fun trying to reach for something that hasn't been done before. So, the metrics are part of the enjoyment.
I've decided that if I pay way less attention to how I'm doing and more attention to how I'm adding value to other people's posts and comments, meaning comments and curation, then the rewards will come and I feel better about what I'm doing here all around. Because it's not just about me. Go figure. :)
