Ask HN: What is the easiest/quickest way to buy bit coin?

I think a lot of it depends what currency you are using to buy the btc. For AUD I've heard positive things about https://www.coinjar.com/, for USD I've heard that https://www.bitstamp.net/ is alright. I am not making any claims about either - just heard from others that they have been decent to use (quick, alright customer service).

Most places won't take debit/credit card. You will have a much better time using your bank account for a transfer or wire.

If you're in the USA I suggest http://coinbase.com for its ease. If not I'd look towards http://bitstamp.net. http://kraken.com is also another decent exchange.
