I can't even see where you mean! Or is it because it's not my picture?! Nice goose though
Poor thing! You missed it, Mick must have changed it. It has indeed gone.
But, if you go to the images at the bottom of the front page (Strobist rss), you can see it in the blurb with the flower picture, where 'X-Pro2' as well as 'single speedlight' are highlighted.
(I don't know if they will be highlighted in this post, till I post it.)
