Will Flickr cofounders make a run for the border, or head for the Big Apple?

Now that Caterina Fake has left Yahoo and Stewart Butterfield has tendered his abstract resignation letter, what will the widely beloved Flickr cofounders do? And where will they go? Brendon Wilson, who worked in the Valley himself before returning to his native Canada, pointed us to an effort by a group of geeks to convince Fake and Butterfield to come back to Vancouver, British Columbia, where Flickr was launched. The welcome wagon even turned out a video slideshow of Flickr photos to remind the couple just how beautiful the city can be. Look, a rainbow! And it may just be working — last night, Butterfield added himself to the Bring Stewart and Caterina Home! group on Facebook. Fake may have other plans, though.

She was recently spotted in New York's startup-laden Flatiron and Chelsea neighborhoods, making the rounds. New York VC Fred Wilsion is an unabashed fan, and the two have already invested alongside his Union Square Ventures in Etsy. Might the pair break hearts in both San Francisco and Vancouver by moving to Manhattan instead? As for New York, all I can say is been there, done that. Head back to Canada for Sonnet's sake, guys. American citizenship ain't what it used to be.
