Out of curiosity, at which Alexa rank range do you take new sites serious? 100,000? 50,000?
From a little bit of research it looks like piccys.com has 30 million page views with an Alexa rank of 8518, and weheartit.com has 850 million page views with a rank of 1367. So the top 10,000 seem difficult to get into as a newcomer.
