Lubo Motl’s Reference Frame is an extremely popular physics blog–in fact, the number one Google result for “frank wilczek blog.” Lubo is offering a prize to his 400,000th visitor–and the same prize to visitor number 400,001, 400,002, 400,003, or 400,004–the opportunity to write a guest post there. But hustle on over there if you want to win; he’s already up to 399,679.
In other Lubo news, he is very kindly attempting to double (or do I mean halve? the nice one of those two) the Amazon rank of the now almost-officially-released Fantastic Realities.
Thanks, Lubo, and I hope those big-number visitors add interesting and amusing posts to your own collection.
