For those of us outside California Quora seems little more than a silicon valley circle jerk.A better branded version of the old experts exchange,though its not hard to brand yourself better than the company with the second worst url in internet history(I wonder how mole station nursery is doing these days?). The very the people who have benefited from the internet revolution move to limit access to publicly provided information,information they themselves did not even create.Nice job kicking out the ladders from under you. If I ever get hit on the head and want to live life as some someone else's virtual pet ill be sure to check out foursquare as well(oh you went to the pub,who's a good boy?Have a virtual cookie). Stack Overflow does a lot wrong,half of my favourite answers are marked as closed for some arbitrary reason but at least it can provide open and accurate answers to questions in specific problem domains. In the land of the blind the one eyed man is truly king.
