I just noticed that LJ has placed this curious thing on our profile pages (probably years ago, while I wasn't paying attention to anything that far up) that calculates your journal rank and your social capital. What does that even mean? Rankings, I can wrap my head around, as it must be calculated by some amalgamation of how frequently you post and how many people comment on your posts, but social capital? I know, I know: I should probably just click the little question-mark next to it. I'm afraid that if I do, though, it might ruin the mystique. I have 46 social capital. Is it a currency? Can I trade it for things?
