Got approached by StockphotoPro through my Flickr Mail, (Dear Matt, your photos are classics, add them to our archive and make us lots of money, you vain person) on the basis of these images:
Flattered, obviously, though not sure how much critical response was there. Suspect a bit of filtering has been done based on the number of Faves each image has already attracted. This wisdom of crowds method probably suits something as intentionally bland and average as stock photography.
