Nice post. I like how you broke down the different kinds of accounts.

Yes, I think there is something significant about 500 SP. Like you said, you get the slider and access to some support groups. It is also a psychological marker where you may start to feel less like a novice.

Obviously there is a lot of room to grow above 500, but before that point it is harder to think about supporting people newer than yourself. I've donated to a couple of projects before, but I had so little to give that it was mostly just the thought that count. At 500 SP, you could start to make a difference. It feels so far away though.

Nice to see that my growth has been somewhat exponential. Here is to hoping for continued growth!
