That's true, but Lifehacker didn't cover us until after we launched publicly. We pitched them with a demo code towards the end of our beta and never heard anything back. Judging from the traffic they've sent recently we probably could have gotten 18k beta signups from them alone.

The biggest hits for our beta were sites we never heard of that found us on smaller blogs and reached out to us. Sites like http://www.dinside.no http://www.genbeta.com and http://www.walla.co.il.

I should write about our experience with non-english blogs later.
