I just shot you an email, but this seems like a reasonable place to note that my employer (Twitter) is hiring like mad, and we definitely have some big data to work with:
Hmmm... I applied at Twitter and got the coding problem done right. I also contributed to one of Twitter's open source projects, "Snowflake." Either you got to have a great story like this Iowa guy, or hiring at Twitter is broken. :-( This might be my next HN post: "How I Interviewed Great at Twitter but a bad coder got my job."
Maybe the fact that you didn't get hired has something to do with you coming off as a total asshole. What exactly makes you think the OP is a "bad coder"?
Maybe you should write a post titled, "How Twitter Failed to Fulfill My Sense of Entitlement".
