Cool, I knew my 30k SO rep would be good for something
Let's just ignore that 1 SER (Stack Exchange Rep) is valued at (0.2 BTC / 10000) * $11 = $0.00022.
It is kind of the community to donate some BTCs for the tremendous resource that is Stack Exchange. This initiative does provide the following side-effects (at least):
1) promotes the visibility of Bitcoins ("Hey, what's that Bitcoin address meme about? More unicorns?")
2) helps locate SO contributors with high rep who are interested in Bitcoin (
bitcoin.stackexchange.com also helps here)
3) promotes the propster site
As a side note, several progressive recruitment agents have noted that a high rep on Stack Exchange has been mentioned by prospective clients. They use it as a quick filter for "technical knowledge with solid communication skills".
So maybe it is good for something else.
